Provide builder for constructing instances of MiniDFSCluster
------------------------------------------------------------
Key: HDFS-1456
URL: https://issues.apache.org/jira/browse/HDFS-1456
Project: Hadoop HDFS
Issue Type: Improvement
Components: test
Affects Versions: 0.22.0
Reporter: Jakob Homan
Assignee: Jakob Homan
Fix For: 0.22.0
Time to fix a broken window. Of the 293 occurences of "new MiniDFSCluster("...
most look something like:
{noformat}cluster = new MiniDFSCluster(0, config, numDatanodes, true, false,
true, null, null, null, null);{noformat}
The largest constructor takes 10 parameters, and even the overloaded
constructors can be difficult to read as their mainaly nulls or booleans.
We should provide a Builder for constructing MiniDFSClusters to improve
readability.
