Csaba Ringhofer created IMPALA-10776:
----------------------------------------

             Summary: Hold write lock for less time in ALTER TABLE RECOVER PARTITIONS
                 Key: IMPALA-10776
                 URL: https://issues.apache.org/jira/browse/IMPALA-10776
             Project: IMPALA
          Issue Type: Improvement
          Components: Frontend
            Reporter: Csaba Ringhofer


ALTER TABLE RECOVER PARTITIONS holds a write lock on the table for the whole time while it lists the HDFS directories and creates the new partitions in HMS. This can potentially take a long time and block catalog updates.
