Lars Hofhansl moved HDFS-5571 to HBASE-10047:
---------------------------------------------

        Key: HBASE-10047  (was: HDFS-5571)
    Project: HBase  (was: Hadoop HDFS)

>          Issue Type: Bug

> Continuing my profiling quest, I find that in scanning tall table (and filtering everything
on the server) a quarter of the time is now spent in the postScannerFilterRow coprocessor
hook.
