Anoop Sam John commented on HBASE-19806:
----------------------------------------
bq.namespace entries should not change much.
Ya with that my doubt was whether we should be worried abt this 10 max size at
all. Just leave it is ok?
When seeing the code, we have config for META block size also. Same apply to
NS also? Just asking. So my suggestion would be , if we create a new jira to
handle the NS specially (like META) for these settings, let us take all and
propose a full patch.
> 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.
