Subject [jira] [Commented] (HBASE-17680) Run mini cluster through JNI in tests
Date Fri, 24 Feb 2017 01:02:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15881670#comment-15881670
] 

Enis Soztutar commented on HBASE-17680:
---------------------------------------

Couple of more comments: 
 - At least some of the methods are C-style, and rest are C++ style. We can just stick with
C++ and encapsulate everything inside the class. 
 - Also, you can use much nicer ifstream instead of fopen / flose, and use std::string instead
of mallocing c-strings. You can use {{string::c_str()}} to pass back to the JVM args. 
 - Instead of {{(*env).Foo()}}, you should use {{env->Foo()}}.

> Currently tests start local hbase cluster through hbase shell.
> There is less control over the configuration of the local cluster this way.
> This issue would replace hbase shell with JNI interface to mini cluster.
> We would have full control over the cluster behavior.
> Thanks to [~devaraj] who started this initiative.
