Hello Andrew Sherman, Riza Suminto, Jason Fehr, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/21302
to look at the new patch set (#4).
Change subject: IMPALA-13005: Create Query Live table in HMS
......................................................................
IMPALA-13005: Create Query Live table in HMS
Creates the 'sys.impala_query_live' table in HMS using a similar 'CREATE
TABLE' command to 'sys.impala_query_log'. Updates frontend to identify a
System Table based on the '__IMPALA_SYSTEM_TABLE' property. Tables
improperly marked with '__IMPALA_SYSTEM_TABLE' will error when
attempting to scan them because no relevant scanner will be available.
Creating the table in HMS simplifies supporting 'SHOW CREATE TABLE' and
'DESCRIBE EXTENDED', so allows them for parity with Query Log.
Explicitly disables 'COMPUTE STATS' on system tables as it doesn't work
correctly.
Updates workload management implementation to rely more on
SystemTables.thrift definition, and adds DCHECKs to verify completeness
and ordering.
Testing:
- adds additional test cases for changes to introspection commands
- passes existing test_query_live and test_query_log suites
