How to allow apache apache to handle multiple client requests

I created an external table via hive from hbase. When someone went into the shell and deployed some queries, no one else could run any query. when someone tries to run quesry, he gives the following error.

FAILED: error in metadata: java.lang.RuntimeException: unable to execute instance of org.apache.hadoop.hive.metastore.HiveMetaStoreClient FAILED: Runtime error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

when the first shell exits, queries can be performed easily. Thus, this means that my bush a cannot handle multiple clients. How to allow processing of multiple clients
