Anoop Sam John commented on HBASE-19806:
----------------------------------------
The config 'hbase.meta.versions' looks to be specific for META. So I dont
think same to be applied to NS table also. But the versions change for NS
table is very relevant as for META? For META entries, it is expected to get
more versions as the time progress and region moves etc. NS entries will get
changed much? WDYT Ted?
> 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'}
> ...
> {NAME => 'table', VERSIONS => '10', 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 => '
> 8192'}
> {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.
