Add max I/O time to Hbase runtime stats

Collect and display the maximum Hbase operator I/O time. In a parallel

plan, this is chosen from the biggest Hbase I/O elapsed time among all

the same Hbase tcb instances at the runtime stats merge stage. For

serial plan the value equals to the Hbase I/O elapsed time.

In addition, the displayed Hbase I/O is changed from byte to MB.

SQL syntax to cancel executing query, phase 3

This change fixes some problems with subset DELETE and

UPDATE statements which prevented them from responding

to CANCEL. It addresses an identical potential issue in

SELECT statements with predicates that reject large

numbers of rows.

The change also allows an envvar, SQL_NO_REGISTER_CANCEL,

which if set to 1, prevents queries from registering with

the cancel broker. It can be used to debug performance


The change also adds test cases to the regression test

Log reading TMUDF, phase 3

blueprint cmp-tmudf-compile-time-interface

- Addressed review comments from phase 2. See

- Added a "parse_status" column to the TMUDF, see

updated syntax below

- Added versioning info to new DLL

- EVENT_LOG_READER TMUDF now should choose the correct

degree of parallelism without the need for CQDs

- Brought back the REPLICATE PARTITION keyword, which

is used in the TMUDF syntax. This should fix the failure

in regression test udf/TEST108.

- Some remaining issues:

- Newlines in the error message are not handled well,

at best the additional lines are lost, at worst

they will cause parse errors

- log_file_node output column is always 0

- Code is not yet integrated with changes to event


- Not yet tested on clusters

Updated syntax for the log reader TMUDF:

SQL Syntax to invoke this function:

select * from udf(event_log_reader( [options] ));

The optional [options] argument is a character constant. The

following options are supported:

f: add file name output columns (see below)

t: turn on tracing

d: loop in the runtime code, to be able to attach a debugger

(debug build only)

p: force parallel execution on workstation environment with

virtual nodes (debug build only)

Returned columns:

log_ts timestamp(6),

severity char(10 bytes) character set utf8,

component char(24 bytes) character set utf8,

node_number integer,

cpu integer,

pin integer,

process_name char(12 bytes) character set utf8,

sql_code integer,

query_id varchar(200 bytes) character set utf8,

message varchar(4000 bytes) character set utf8

if option "f" was specified, we have four more columns:

log_file_node integer not null,

log_file_name varchar(200 bytes) character set utf8 not null,

log_file_line integer not null,

parse_status char(2 bytes) character set utf8 not null

(log_file_node, log_file_name, log_file_line) form a unique key

in the result table. parse_status indicates whether there were

any errors reading the information:

' ' (two blanks): no errors

'E' (as first or second character): parse error

'T' (as first or second character): truncation or over/underflow


'C' (as first or second character): character conversion error

Adding check for HDP 2.2/CDH 5.2 and Java Version

Adding Java Version check from into the installer.

Adding check to error out of user tries to install Trafodion

with Hortonworks 2.2 or Cloudera 5.2 installer on their system.

Edit 1: Add check that HBase is installed on all nodes. Also, print

large error if trafodion_setup fails.

Edit 2: Changed Java version needed from 1.7.0_67 to 1.7.0_65.

More fixes to make SQL thread safe

Fix for bug 1403334 – T2 multithread tests core dump in SQLCLI_DropContext

NAMemory was not threadsafe in derived memory management. The calls

registerMemory, unRegisterMemory was not threadSafe when the heap is marked

as threadsafe heap. Also, the mutex is now dropped as part of NAHeap


Fix for bug 1403410 - With 128 threads thru T2 driver, MTTrans and YCSB tests

crash and generate this core

The context list was being manipulated without acquiring a mutex in some places

These obsolete codes are now removed.

Some of the globals were wrongly declared as thread globals.

Other Fixes

SQL_EXEC_GetDiagnosticsCondInfo2 CLI call is now protected by mutexes

like any other CLI call.

Also removed some of the obsolete codes in the cli layer.

Currently commented out the code to close all the open cursors in all

the contexts when a change in transaction id is detected. We need to detect

the change in transaction at context level and close cursors belonging to

that context only.

Fix for Mdam access causes large number of rows to be accessed.

A fix by Dave Birdsall and Anoop Sharma on a problem where mdam probe was

causing large number of rows to be accessed. The issue was that the scan cache

was being set to 10000 based on cardinality estimates, but the mdam probe

is being to retrieve only one row at most. Additinal changes to improve

debugging with mdam predicate network.

Dummy delta change to get check tests to run again.
