I cannot answer this question, as far as I know 0.20.6 doesn't have a bug that prevents you from writing data (and many people use it in production environments). My guess is, the data never got into HBase or it was written with wrong timestamps and is hidden by delete markers or something "time-travelly" like that. If they do play with timestamps, ask them not to or verify they do the right thing. > QA used stop-hbase.sh to stop HBase. Would Memstore contents be flushed to > Storefile at that moment ? Yep, if you don't see any store file then the data never made it into hbase. > > QA servers were running JVM version 1.6.0_18 >From >http://hbase.apache.org/docs/r0.20.6/api/overview-summary.html#requirements "Java 1.6.x, preferably from Sun.
