Inserting data into existing partition gives ClassCastException

New Contributor


I am using HDP 3.0 & HIVE 3.1.0 and whenever I am trying to insert the data into existing partition, I am getting below ClassCastException:

metastore.RetryingHMSHandler ( - java.lang.ClassCastException: org.apache.hadoop.hive.metastore.api.StringColumnStatsData cannot be cast to org.apache.hadoop.hive.metastore.columnstats.cache.StringColumnStatsDataInspector

Please help on this.
