stack commented on HBASE-1686:
------------------------------
Chatting with Manish, his table schema is as follows:
{NAME => 'lookup_records', FAMILIES => [{NAME => 'piston', VERSIONS => true
'3', COMPRESSION => 'NONE', TTL => '2147483647', BLOCKSIZE => '65536'
, IN_MEMORY => 'false', BLOCKCACHE => 'true'}]}
And he is not deleting.
So, odd that he runs into this issue.
> major compaction can create empty store files, causing AIOOB when trying to
> read
