Description

On an hbase 2 cluster, I got the description of hbase:meta table:

{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'}

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.
