Fix for #1359358 dcs_installer server file format

Changed code to generate the new DCS servers file format

of one line per node with a count of servers for that node

instead of the older format of listing a node multiple times

Old format:









New format:

node1 3

node2 3

node3 2

Bulk Unload/extract (prototype)

These changes add support for a bulk unload/extract (prototype) to unload data

from trafodion tables into HDFS. Bulk unload unloads data in either

compressed (gzip) or uncompressed formats. When specified, compression take

place before writing data bufers to files. Once the data unloading is done

the files are merged into one single file. If compression is specified

the data are unloaded into files in compressed format and then merged in

compressed format. Otherwise they are unloaded in uncompressed format

and merged into one uncompressed file.

The unload syntax is:

UNLOAD [[WITH option] [, option] ...] INTO <hive-table> query_expression


*<hive-table> is a hive table.


*option can be:

- PURGEDATA FROM TARGET: When this option specfied the files under the

<hive-table> are deleted

- COMPRESSION GZIP: when this option is specfied the Gzip compression is

used. the compression takes place in the hive-insert node and data

is written to disk in compressed format (Gzip i the only supported

compression for now)

- MERGE FILE <merged_file-path>: When this option is specified the files

unloaded are merged into one single file <merged-file-path>. if

compressiion is specied the data unloaded in compressed format

and the merged file will be in compressed formt also.

- NO OUTPUT: If this option is specified then no status messge is dispalyed

Making Maven build output less verbose

Maven emits warnings about using an environment variable as the

version. We want to keep doing this, since we have multiple Maven

projects that should all have the same version, stored centrally

in the file.

Suppressing most Maven output, including the warning, on stdout,

but preserving the entire output in the log file

(except for the "clean" target).

SQL Compiler/Generator speed improvement

There were 7 places where the ItemExprTreeAsList::entries() routine

was being called inside a for loop when the return value from entries()

did not change while going through the loop. For most xyz::entries()

routines, that is not significant since they just return the value

previously stored in an object. However, ItemExprTreeAsList::entries()

actually traverses a node tree and counts the number of nodes.

This set of changes moves the call to that routine outside the loop.

All dev regressions were run to ensure that the fix has no

Fix for traf_cloudera_mods Hbase error, other fixes

Added check that will look to see what the exact name of hbase to use in

traf_cloudera_mods to make a call to set hbase settings and restart

hbase. (Formally clouderas url was .../hbase1 it is now .../hbase).

Changed parsing in trafodion_mods to allow for Cloudera cluster name to

be more than one word.

Moved SQconfig check in trafodion_installer to after it has been moved

to current directory if on a single node.

Changed error message in trafodion_mods.

Fix for bug 1348211 Generator error 7000 "root can't produce these values"

For joins involving repartitioning of data to match the other table,

we got this error in some cases, usually seen with salted tables.

Fix is to avoid storing the PIVs (partition input values) in the logical

scan node. Instead they are picked up in the preCodeGen phase, and this

means that if the PIVs have to be rewritten, we pick up the new and

correct values.

Patch set 3: Fixed regression issue by moving PIV logic so

availableValues includes the PIVs.

Enabling HASH2 partitioning of salted tables

- In FileScan::preCodeGen(), make sure we add part key predicates in all

3 cases, a) MDAM, b) with an existing search key, c) without a search key.

- Make sure we don’t do the HBase “constant keys” optimization when we have

partitioning key predicates (HBaseAccess::preCodeGen()).

- Since the partition input values for a HASH2 function are actual hash

values, the key predicate needs to call the Hash2Distrib function to

compute the salt value


- When we replace an existing search key with a new one for the partitioning

key predicates, try to include the existing predicates as well
