Description

Quote email from Ashutosh Chauhan:

There is a bug in hadoop-env.sh which prevents hcatalog server to start in secure settings. Instead of adding classpath, it overrides them. I was not able to verify where the bug belongs to, in HMS or in hadoop scripts. Looks like hadoop-env.sh is generated from hadoop-env.sh.template in installation process by HMS. Hand crafted patch follows:

- export HADOOP_CLASSPATH=$f

+export HADOOP_CLASSPATH=${HADOOP_CLASSPATH}:$f

-export HADOOP_OPTS="-Djava.net.preferIPv4Stack=true "

+export HADOOP_OPTS="${HADOOP_OPTS} -Djava.net.preferIPv4Stack=true "
