Ted Yu commented on HBASE-19806:
--------------------------------
I don't think this bug should be categorized as trivial.
Without the fix, when other families are configured with higher than 10
versions, the table family would still have 10 versions.
If other families stay with default version count, the extra 7 versions kept in
table family are not useful since there is no corresponding versions in the
other families.
> Lower max versions for table column family of hbase:meta

> On an hbase 2 cluster, I got the description of hbase:meta table:
> {code}
> {NAME => 'info', VERSIONS => '3', EVICT_BLOCKS_ON_CLOSE => 'false',
> NEW_VERSION_BEHAVIOR => 'false', KEEP_DELETED_CELLS => 'FALSE',
> CACHE_DATA_ON_WRITE => 'false', DATA_BLOCK_ENCODING => 'NONE', TTL =>
> 'FOREVER', MIN_VERSIONS => '0',
> REPLICATION_SCOPE => '0', BLOOMFILTER => 'NONE', CACHE_INDEX_ON_WRITE =>
> 'false', IN_MEMORY => 'true', CACHE_BLOOMS_ON_WRITE => 'false',
> PREFETCH_BLOCKS_ON_OPEN => 'false', COMPRESSION => 'NONE', BLOCKCACHE =>
> 'true', BLOCKSIZE => '81
> 92'}

> {code}
> You can see that 'table' family has MAX VERSIONS much higher than the other
> families.
> The MAX VERSIONS value should be brought in sync with the other families.
