Hi
org.apache.hadoop.ipc.RemoteException(java.io.IOException): File
/user/pts/output/OTSOutput/_temporary/1/_temporary/attempt_1463_0008_m_000018_2/video.mp4.of.txt
could only be replicated to 0 nodes instead of minReplication (=1). *There are
9 datanode(s) running* and no node(s) are excluded in this operation.
Can it be there is no more space left (for HDFS) on the host running data nodes?
Try running "hdfs dfsadmin -report"

Hi hadoop users,
We are running a mapreduce jobs with 10 nodes. Each map job process a video
and generate a .txt file as output. We are getting DataStreamer Exception that
File could only be replicated to 0 nodes instead of minReplication (=1). This
is the output file we expect after successful run.
Any help is appreciated. We checked hdfs has space available and all nodes are
responding.
