[jira] [Updated] (HBASE-21946) Replace the byte[] pread by ByteBuffer pread in HFileBlock reading once HDFS-3246 prepared

     [ https://issues.apache.org/jira/browse/HBASE-21946?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Zheng Hu updated HBASE-21946:
-----------------------------
    Description: 
[~stakiar] is working on HDFS-3246,  so now we have to keep the byte[] pread in HFileBlock reading.  Once it get resolved, we can upgrade the hadoop version and do the replacement. 
I think it will be a great p999 latency improvement in 100% Get case, anyway file a issue address this firstly.
