I am writing multiple files using multiple FSOutputStreams through different
threads in HDFS. All the files are getting written properly and I see that
namenode and datanode logs have no error. The namenode log suggests that all
the files are closed.
However, a close on one my streams fails consistently with the following
exception.
java.io.IOException: Call to flint/<ipaddress>:9000 failed on local
exception: java.io.InterruptedIOException: Interruped while waiting for IO
on channel java.nio.channels.SocketChannel[connected
local=/<ipaddress>:57082 remote=flint/10.1.41.176:9000]. 59979 millis
timeout left.
