Commit 6d715fe7dc2ff2fa549952d5eac384a77bc0357b in impala's branch
refs/heads/master from Andrew Sherman
[ https://gitbox.apache.org/repos/asf?p=impala.git;h=6d715fe7d ]
IMPALA-13596: Add warnings and exceptions to reading of fair-scheduler file.
The fair-scheduler file contains part of the configuration for Admission
Control. This change adds some better error handling to the parsing of
this file. Where it is safe to do so, new exceptions are thrown; this
will cause Impala to refuse to start. This is consistent with other
serious configuration errors. Where new exceptions might cause problems
with existing configurations, or for less dangerous faults, new warnings
are written to the server log.
For the recently added User Quota configuration (IMPALA-12345) throw an
exception when a duplicate snippet of configuration is found.
New warning log messages are added for these cases:
- when a user quota at the leaf level is completely ignored because of
a user quota at the root level
- when there is no user ACL on a leaf level queue. This prevents any
queries from being submitted to the queue.
