Description

If source is 1.x and peer is 2.x and a default table is created at source and also at peer, default table descriptors mismatch so the enable table replication fails with error :

 

Table t1 exists in peer cluster 1, but the table descriptors are not same when compared with source cluster. Thus can not enable the table's replication switch.

Following are the extra attributes set by default in 2.x:
CACHE_DATA_ON_WRITE
CACHE_INDEX_ON_WRITE
CACHE_BLOOMS_ON_WRITE
EVICT_BLOCKS_ON_CLOSE
PREFETCH_BLOCKS_ON_OPEN.
