Fixed bug with default & previous values for build tar files

If a build file was specified (as opposed to a package file) by the user

the values from previous runs was not being picked up as the

default values on subsequent runs. This fixes that for the

trafodion build and DCS build tar files.

Snapshot Scan changes

The changes in this delivery include:

-decoupling the snapshot scan from the bulk unload feature. Setup of the

temporary space and folders before running the query and cleanup afterwards

used to be done by the bulk unload operator because snapshot scan was specific

to bulk unload. In order the make snapshot scan indepenednt from bulk unload

and use it in any query the setup and cleanup tasks are now done by the query

itself at run time (the scan and root operators).

-caching of the snapshot information in NATable to optimize compilation time

Rework for chaching: when the user sets TRAF_TABLE_SNAPSHOT_SCAN to LATEST

we flush the metadata and then we set the caching back to on so that metadata

get cached again. If newer snapshots are created after setting the cqd they

won't be seen if they are already cached unless the user issue a command/cqd

to invalidate or flush the cache. One way for doing that can be to issue

"cqd TRAF_TABLE_SNAPSHOT_SCAN 'latest';" again

-code cleanup

below is a description of the CQds used with snapshot scan:


this CQD can be set to :

NONE--> (default)Snapshot scan is disabled and regular scan is used ,

SUFFIX --> Snapshot scan is enabled for the bulk unload (bulk unload

behavior is not changed)

LATEST --> Snapshot Scan is enabled independently from bulk unload and

the latest snapshot is used if it exists. If no snapshot exists

the regular scan is used. For this phase of the project the user

needs to create the snapshots using hbase shell or other tools.

And in the next phase of the project new comands to create,

delete and manage snapshots will be add.


This CQD is used with bulk unload and its value is used to build the

snapshot name as the table name followed by the suffix string


When the estimated table size is below the threshold (in MBs) defined by

this CQD the regular scan is used instead of snapshot scan. This CQD

does not apply to bulk unload which maintains the old behavior


The timeout beyond which we give up trying to create the snapshot scanner


Location for temporary links and files produced by snapshot scan

Using one thread pool for all HTables access

Earlier we had a ThreadPool for every HTable. Now we have one

thread pool for all HTables across all JDBC/ODBC connections

to improve thread resource usage.

Also cleaned up code to ensure the configuration is read at the

lower layers. Removed the need to pass host name and port

number because it will be picked up from hbase-site.xml

Fix for bug 1429882

Disabled pre-fetch in case of snapshot scan

Merge "Added new Trafodion REST server infrastructure"

NODE_LIST, removed hostname checks, scanner

Changed how NODE_LIST is created. A list of nodes is entered by the user

and that list is used to ssh to each node given which then the

"hostname" command is used to get hostname which is used to create

NODE_LIST that is used to generate sqconfig. Users can now enter in IP

addresses or node names. All hostname checks are now removed.

The scanner can now be called from trafodion installer.

Edit 1: Removed code used for testing

Edit 2: Corrected TRAF_VERSION (for when a debug build is used) and

added changes to how scanner is called.

Merge "Fix HQC Bugs: LP1421374 LP1409863 LP1409830"

Enable authorization by default for regress, plus

Patch 1:

Added TEST138 to catman1 - skipped files

Fixed wording in the traf_authentication_setup script from reviewer comments.

Original delivery:

change 1 - Enable authorization during development regression tests

change 2 – Added support for create schema IF NOT EXISTS and drop schema IF EXISTS

change 3 - Changed traf_authentication_setup script to support a new installation option

change 1 - Enable authorization during development regression tests

Authorization will be enabled during regressions runs

Since regressions run mostly as DB__ROOT, there should be few visible differences.

Developers may see GRANT statements displayed as part of SHOWDDL requests.

This can be controlled by a new CQD:SHOWDDL_DISPLAY_PRIVILEGE_GRANTS


ON - display GRANTS if authorization is enabled

OFF - do not display GRANTS


if running with SQLMX_REGRESS set, do not display grants

otherwise, display grants

regress/tools/init_sb_regr_sql -- execute initialize authorization

regress/tools/runregr_catman1.ksh -- turn on TEST138

regress/catman1 -- various test and expected files to set the new SHOWDDL CQD

"Initialize authorization, drop;" can be performed to disable authorization

















change 2: Added support for create schema IF NOT EXISTS and drop schema IF EXISTS

Added support for new schema syntax. Change update stats for HIVE tables to use this syntax











change 3: Changed traf_authentication_setup script

This file was changed to support a new option "--setup" that only enables authentication

This will be used by the installation script when the customer chooses not to

initialize trafodion.


traf_authentication_setup --help

This script enables or disables security features for Trafodion

Usage: traf_authentication_setup [options]


--file <loc> Optional location of the OpenLDAP configuration file

--help Prints this message

--off Disables authentication and authorization

--on Enables authentication and authorization

--setup Enables authentication

--status Returns status of authentication enablement

Cleanup hive reader thread when canceling scan

Cancel processing, whether triggered by [FIRST N], error

handling, SQL cancel, or any other reason, can cause the

main executor thread to abruptly stop interacting with

the reader threads. This change fixes a hang caused by

a reader thread waiting for the main thread to give it

an empty buffer, after the main thread has finished the

canceled query.

Convert DSC documentation from docbooks to asciidoc

Docbooks was very difficult for contributors to easily add

the needed documentation. Asciidoc while very feature rich in

its tag set is much much easier to learn.

Reordered the way HDFS and HBase are restarted for Hortonworks

Previously, components were restarted in this order:

restart HBase

restart HDFS

This might have been causing intermittent issues on the Jenkins

gate machines resulting in hanging sqstart.

This change reorders it to this:

stop HBase

stop HDFS

start HDFS

start HBase

Added logic to wait for HDFS to leave safemode before continuing.

When HDFS Namenode restarts, it is temporarily in safemode which

makes HDFS read-only for a time. This caused the hdfs mkdir/setfacl

commands to sometimes fail.

Added some additional error checks for HDFS commands and corrected some

message texts.

Added new Trafodion REST server infrastructure

This commit provides the infrastructure for a Trafodion REST

server. The code was taken from stand alone DCS rest server and

slightly modified to retain just the REST server components and

its supporting scripting and JDBC T2/T4 capabilities. Additional

work is needed by installation group but it currently can be

started in standalone mode while requirements are fully fleshed out.
