Project: Hadoop HDFS
Issue Type: Bug

The user may not be able to read latest data until DFSInputStreamCacheKey
invalidates/expire from NFS cache, default ttl is 10 minutes (
DEFAULT_DFS_INPUTSTREAM_CACHE_TTL). This scenario when we send continues stream
into file and read the same file during write.
Repro -
# nfs mount
# continuous file append.
# read the file
# close append
# again, read the file
