> 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 :
>  
> {code:java}
> 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.{code}
> 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.
