Subject [jira] [Created] (HDFS-5328) MiniDFSCluster times out at startup
Date Tue, 08 Oct 2013 23:29:41 GMT
Alejandro Abdelnur created HDFS-5328:

             Summary: MiniDFSCluster times out at startup
                 Key: HDFS-5328
                 URL: https://issues.apache.org/jira/browse/HDFS-5328
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: test
    Affects Versions: 2.1.1-beta
            Reporter: Alejandro Abdelnur

It seems MiniDFSCluster startup got slower lately and we are observing the following intermittent
failure on startup in our jenkins boxes:

java.io.IOException: Timed out waiting for Mini HDFS Cluster to start
	at org.apache.hadoop.hdfs.MiniDFSCluster.waitClusterUp(MiniDFSCluster.java:972)
	at org.apache.hadoop.hdfs.MiniDFSCluster.initMiniDFSCluster(MiniDFSCluster.java:665)
	at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:585)
	at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:511)

By looking at the code the {{waitClusterUp()}} has a hardcoded 10secs timeout (10 1 sec waits).

There are two things we should look at it, make the timeout configurable, and more important,
see what has changed to make the startup slower.
