> 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
