-Unique Put ends up twice in HBase?
Mesika, Asaf 2013-02-04, 07:20
Can the following scenario occur?
Create a Put for (rk1, cf1, cq1, value=1L)
Put is sent to server
Server throws an exception, but Put still is saved (WAL, memstore)
Flush kicks in
Client attempts a retry and succeeds, thus same put is written for the second time with different timestamp
Fetching the data, assuming we allow maxVersion=2, we get value = 2 for that rk1, cf1, cq1 ?
