IMPALA-3552: Make incremental stats max serialized size configurable
The fix "IMPALA-2648/IMPALA-2664" introduced a conservative limitation
on the maximum serialized size of incremental stats. As a side effect,
some users with very large tables are experiencing regressions
especially when they upgrade impala and the serialized size goes
beyond 200MB.
To mitigate the issue, the change introduces a new gflag,
'inc_stats_size_limit_bytes' to make the max serialized size
configurable, which allows impala users to specify their own maximum
serialized size. Default value for inc_stats_size_limit_bytes is
200MB.
The change introduces a TBackendGflags class to pass the gflags from
backend to the Frontend and the Catalog via thrift. This also revamps
existing query options to use the TBackendConfig.
