Kihwal Lee commented on HDFS-11379:
-----------------------------------
Nicely done. Although the retry in {{readWithStrategy()}} makes it try one more
time before throwing an exception back to the reader, it is far better than
going into an infinite loop.

[~djp], this looks to be important enough to put in 2.8.0. Is it okay to commit
this to the release branch?

> DFSInputStream creation caches file size and initial range of locations. If
> the file is truncated (or replaced) and the client attempts to read outside
> the initial range, the client goes into a tight infinite looping requesting
> locations for the nonexistent range.
