[jira] [Created] (HDFS-13645) Allow user to configure/disable InputStream TTL in NFS Cache

Karthik Palanisamy created HDFS-13645:
-----------------------------------------

             Summary: Allow user to configure/disable InputStream TTL in NFS Cache
                 Key: HDFS-13645
                 URL: https://issues.apache.org/jira/browse/HDFS-13645
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: nfs
    Affects Versions: 2.7.3
            Reporter: Karthik Palanisamy
            Assignee: Mukul Kumar Singh


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
