Change subject: IMPALA-3552: make incremental stats max serialized size configurable ...................................................................... IMPALA-3552: make incremental stats max serialized size configurable The fix fox "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 upgrading. To mitigate the issue, the change introduces a new gflag, 'inc_stat_max_size' to make the max serialized size configurable, which allows impala users to specify their own maximum serialized size. Default value for inc_stat_max_size is 200MB.
