Description

Always getting this exception when exported HBASE_CONF_PATH with configuration directory. connection creation always excepting hadoop-hdfs jar to be present in that case.I think we can check and load the hdfs-jar from any of the places HADOOP_HOME , HBASE_HOME/lib and current directory.

For UDFs we need hadoop-common and hadoop-hdfs jars compulsory.
