LiuLei created HBASE-6868:
-----------------------------
Summary: skip checksum per file
Key: HBASE-6868
URL: https://issues.apache.org/jira/browse/HBASE-6868
Project: HBase
Issue Type: Bug
Components: HFile, wal
Affects Versions: 0.94.1, 0.94.0
Reporter: LiuLei
The HFile contains checksums for decrease the iops, so when Hbase read HFile ,
that dont't need to read the checksum from meta file of HDFS. But HLog file of
Hbase don't contain the checksum, so when HBase read the HLog, that must read
checksum from meta file of HDFS. We could add setSkipChecksum per file to
hdfs or we could write checksums into WAL if this skip checksum facility is
enabled
