Chris Nauroth updated HBASE-14307:
----------------------------------
Attachment: HBASE-14307.001.master.patch
I am attaching a patch. This introduces a {{positionalReadWithExtra}} method
that loops until completing the read. This is similar to the existing
{{readWithExtra}} method that's used in the seek + read code path.
I'm still looking into adding a unit test in {{TestHFileBlock}}. I verified
that the existing tests in that suite pass.
[~srevanka], would you be able to take this patch for a test run in your
environment to verify that it works for your needs? Thanks!

> Considering that {{read()}} is not guaranteed to read all bytes,
> I'm interested to understand this particular piece of code and why is partial
> read treated as an error :
> https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/io/hfile/HFileBlock.java#L1446-L1450
> Particularly, if hbase were to use a different filesystem, say
> WebhdfsFileSystem, this would not work, please also see
> https://issues.apache.org/jira/browse/HDFS-8943 for discussion around this.
