We flush or do kills/kill-9 and data is lost. flush and kill are likely the same problem (kill would flush), kill -9 may or may not have the same root cause. > 5 nodes > hadoop 2.1.0 (a pre cdh5b1 hdfs). > hbase 0.96.1 rc1 > Test: 250000 increments on a single row an single col with various number of client threads (IncrementBlaster).
