Description

If you set HADOOP_CLIENT_OPTS and run hadoop, you'll find that the HADOOP_CLIENT_OPTS value gets appended twice, and leads to JVM start failures for cases like adding debug flags.

For example,

HADOOP_CLIENT_OPTS='-agentlib:jdwp=transport=dt_socket,address=localhost:9009,server=y,suspend=y' hadoop jar anything

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
