> MiniDFSCluster times out at startup

>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: test
>    Affects Versions: 2.1.1-beta, 2.7.1, 3.0.0-alpha1
>            Reporter: Alejandro Abdelnur

> It seems MiniDFSCluster startup got slower lately and we are observing the 
> following intermittent failure on startup in our jenkins boxes:
> {code}
> 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)
> {code}
> 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.
