Description

 Currently the directory used for sidelining of old recovered edit files is hardcoded to be "/tmp"

Path tmp = new Path("/tmp");

 See L484 WALSplittter.java

Instead, we can use some configurable directory in the following manner:

 

String tmpDirName = conf.get(HConstants.TEMPORARY_FS_DIRECTORY_KEY, 
        HConstants.DEFAULT_TEMPORARY_HDFS_DIRECTORY); 
.
.

Path tmp = new Path(tmpDirName);
