Subject [jira] [Comment Edited] (HDFS-11572) [SPS]: SPS should clean Xattrs when no blocks required to satisfy for a file

I took a chance to fix couple of issues in this patch.
Handled to clean Xattrs in the following cases.
1. When none of the blocks really need any movements. 
     Example of file already well satisfied the storages, user still called to satisfy blocks.
In this case we missed to clean Xattrs. This patch addresses that.
2. When file contains no blocks, we missed to clean Xattrs. 

And to make changes easy and readable, I made the block analysis result to represent with
states instead of boolean true or false flag.

This patch addresses that.
2. When contains no blocks, we missed to clean matters. Tin patch addresses.

instead of boolean true or false flags.

This time, SPS will just scan and make sure no blocks needs to satisfy and will leave that
element. In this case, we are not cleaning Xattrs. This is the JIRA to make sure we will clean
Xattrs in this situation.
