stack commented on HBASE-14849:

[~zhanzhang] If you click on the javadoc warnings link above and dig down passing out the
warnings about our use of unsafe features, you'll find this:

1 warning
[WARNING] Javadoc Warnings
[WARNING] /home/jenkins/jenkins-slave/workspace/PreCommit-HBASE-Build/hbase/hbase-server/src/main/java/org/apache/hadoop/hbase/mapreduce/LoadIncrementalHFiles.java:430:
warning - @param argument "hfilesDir" is not a parameter name.

It may not be because of you but a warning left over by anothers' commit.

> I was working at a client with a ported down version of the Spark module for HBase and
realized we didn't add an option to turn of block cache for the scans.  
> At the client I just disabled all caching with Spark SQL, this is an easy but very impactful
> The fix for this patch will make this configurable
