> in hbase early 0.98 versions, 
> protected int binarySearch(final Cell [] kvs,
>       final byte [] family, final int foffset, final int flength,
>       final byte [] qualifier, final int qoffset, final int qlength) {
> uses a static buffer, which might be problematic in concurrent environments. The hbase
community fixed this in https://issues.apache.org/jira/browse/HBASE-9334, however it is quite
possible our users' deployed version does not include this patch.
> we'll change workaround this by not calling related method
