Subject Re: Re: How to debug Hive0.14 with Hadoop2.5.0 in Eclipse?
Date Mon, 22 Dec 2014 19:23:23 GMT
That's true, it might be broken now.  I think now most people to debug
their code will build assembly using -Phadoop-2,dist, and then go to
packaging/target/... and run bin/hive from there.

You can debug changes by setting bin/hive --debug, or alternatively by setting
HADOOP_OPTS to include your own java debug flags.

Hope that helps,
Szehon
