Phabricator updated HBASE-5074:
-------------------------------
Attachment: D1521.14.patch
dhruba updated the revision "[jira] [HBASE-5074] Support checksums in HBase
block cache".
Reviewers: mbautin
Updated patch to to latest trunk. Also, trigger rerun of HadoopQA
unit tests.
The four unit tests that failed in an earlier version of this patch
is not related to this patch. The same set of unit tests also failed
for HBASE-4608, see

> The current implementation of HDFS stores the data in one block file and the
> metadata(checksum) in another block file. This means that every read into the
> HBase block cache actually consumes two disk iops, one to the datafile and
> one to the checksum file. This is a major problem for scaling HBase, because
> HBase is usually bottlenecked on the number of random disk iops that the
> storage-hardware offers.
