When querying a parquet hive table in impala, be sure to run: invalidate metadata <table name>; After this you should see the results.

Hello, From the logs, I found that it was stuck updating the hdfs location. So, I updated the hdfs location manually by running the command metatool -updateLocation After that I was able to bring up the Hiveserver2 service. Best Regards, Rinku Singh.

Hi @Rinku Singh, @Sindhu, We're migrating our cluster to new hardware. TBs of HDFS (/Data, /user & /apps/hive/warehouse) data transferred well to destination. Now, we need to move the Hive tables Metastore. There are 10s of DBs and each would have 100s of tables. The specifications are as follows: Ambari: 2.5.0.3 (Old), 2.6.1.5 (New) HDP: 2.6.0.3 (Old), 2.6.4.0 (New) HIVE DB: MySQL (Old), Postgres (New) Issue: We don't have the DBs schema so that we can run again on new cluster. It would be very tedious to Create Table from one to another. Is there a way to import the metadata dump from one to another? Please advise! Thanks allot in advance! Regards.
