-------------------------------------------------------------
[~yuan_zac] Thanks! I've reproduced your issue and double-checked the patch. It
solves the HDFS connection issue caused by wrong HADOOP_COMMON_HOME value which
causes invalid classpath.
Both set it empty or correct works per my testing.
{code:java}
fw.append("export HADOOP_COMMON_HOME=\n");{code}
[~sunilg] or [~leftnoteasy] Could you help merge the patch? Thanks!
