Peter Somogyi commented on HBASE-20649:
---------------------------------------
When I tried to simply use HBCK2 against hbase-1.2 cluster I got the same
corruption report about HFiles using PREFIX_TREE data block encoding, however,
I got a different exception after this.
{noformat}
org.apache.hadoop.hbase.regionserver.NoSuchColumnFamilyException:
org.apache.hadoop.hbase.regionserver.NoSuchColumnFamilyException: Column family
table does not exist in region hbase:meta,,1.1588230740 in table 'hbase:meta',
{TABLE_ATTRIBUTES => {IS_META => 'true', coprocessor$1 =>
'|org.apache.hadoop.hbase.coprocessor.MultiRowMutationEndpoint|536870911|'},
{NAME => 'info', BLOOMFILTER => 'NONE', VERSIONS => '10', IN_MEMORY => 'true',
KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER',
COMPRESSION => 'NONE', CACHE_DATA_IN_L1 => 'true', MIN_VERSIONS => '0',
BLOCKCACHE => 'true', BLOCKSIZE => '8192', REPLICATION_SCOPE => '0'}{noformat}
This exception comes from a scan in onlineConsistencyRepair():
[https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/util/HBaseFsck.java#L693]
So at it is now {{hbase hbck -checkCorruptHFiles}} is not enough.

> HBASE-20592 adds a tool to check column families on the cluster do not have
> PREFIX_TREE encoding.
> Since it is possible that DataBlockEncoding was already changed but HFiles
> are not rewritten yet we would need a tool that can verify the content of
> hfiles in the cluster.
