I looked at revision history for HFileOutputFormat.java
There was one patch, HBASE-8949, which went into 0.94.11 but it shouldn't
affect throughput much.
If you can use ganglia (or some similar tool) to pinpoint what caused the
low ingest rate, that would give us more clue.
BTW Is upgrading to newer release, such as 0.98.1 (which contains
HBASE-8755), an option for you ?
