Hi @Albap Based on the logs, i can see you have created streaming application. By default streaming application will run 24*7, it will stop only when we kill or some interrupted event happen at the system level. Better way to kill/shutdown the spark streaming applications is by using graceful shutdown. If you need further help, please raise an cloudera case we will work on.

I assume you meant NVL function returns 0 or 1 if a null is found, or the specified expression in the argument - when using Hive. With Impala and NVL2 you would still need to have the outer query to "sum" up all the 1 values what we have mapped from the column value (from their real value to 0 or to 1). It would just be a bit nicer, but no real change.

Closing the connection while the query is still executing is generally not good practice. Think of it as taking ownership for the query you've executed, sort of like turning the lights off before you leave a room. If you're going to close the session (leave the room), you need to first cancel the query that's consuming resources (turn off the lights you turned on). The normal expectation is that an executing query will have an associated active session.

Hi @dearvenkat , Sorry I was thinking that you just want to change the value, but if you are using RENAME PARTITION sql command it will depend on which type of table you have If it's EXTERNAL the data in HDFS will remain in the same old directory. If your table is MANAGED it should change the directory name to the new one. Please refer to this article: https://community.cloudera.com/t5/Support-Questions/Partition-rename-in-Hive-HDFS-path/td-p/193283 Apache Hive SQL Reference: https://cwiki.apache.org/confluence/display/hive/languagemanual+ddl#LanguageManualDDL-RenamePartition

Hey, it looks like you're running Hadoop on Windows! I'm guessing that this is not a Cloudera package and that you're attempting to run some other flavour of Hadoop on a Windows host. The java.lang.UnsatisfiedLinkError suggests you're missing the hadoop.dll library from your path.
