Description

When running hive recursive debug mode, for example,
./bin/hive --debug:port=10008,childSuspend=y
It fails with error msg:
–
ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate jdwp options.Error occurred during initialization of VM
agent library failed to init: jdwp
–
It is because HADOOP_OPTS and HADOOP_CLIENT_OPTS both have jvm debug options when invoking HADOOP.sh for the child process. The HADOOP_CLIENT_OPTS is appended to HADOOP_OPTS in HADOOP.sh which leads to the duplicated debug options.
