Hi @Shelton, sorry for the delay in responding. I finally found the solution to my problem. I need to specify the column properties and then Compute Stats will work perfectly. ```sql ALTER TABLE myschema.mytable ADD COLUMNS (mycolumn1 TIMESTAMP NULL COMPRESSION DEFAULT_COMPRESSION, mycolumn2 TIMESTAMP NULL COMPRESSION DEFAULT_COMPRESSION); ```

Hi Shelton, The answer to all questions is yes. I'm using the Hue Impala Editor and all these commands were issued by HUE. As I've already solved the problem with a CREATE AS SELECT, I'm going to ask for a little time to simulate this problem again. Thanks again,

Hi Shelton, Thanks for your reply, but INVALIDATE METADATA didn't work for me. I still have the same error. My option was to recreate the table with a CREATE TABLE as SELECT from the previous table. Thanks again

Hi @ylchew93, Do you solve this issue? I have the same problem after enabled Kerberos in my cluster.

Hi @pvillard, I have some doubts about what kind of keytab file to create. I don't know much about Kerberos and do not find much information about the kind of Keytab file I should use to connect my Nifi Cluster to a kerberized Cloudera Cluster. Can you help me?

Hi, @zhxj, do you found some way to treat this issue? I have the same issue to convert timestamp data to Parquet. I try this in the schema, but do not work. { "name": "dat_timestamp", "type": { "type":"int64", "logicalType":"timestamp-millis", "isAdjustedToUTC" : "false"} }, Thanks,

Maybe do you are looking for SSoT (Single Source of Thruth). Kafka may be the best option to achieve this concept. The link bellow may help you: https://www.confluent.io/blog/messaging-single-source-truth/

After read the content of the link below a made some changes in both nifi.properties e boostrap.conf files. That changes solved the issue, for now. https://community.hortonworks.com/articles/7882/hdfnifi-best-practices-for-setting-up-a-high-perfo.html nifi.properties file: <nifi.queue.swap.threshold=100000/> Bootstrap.conf file: <# JVM memory settings java.arg.2=-Xms4g java.arg.3=-Xmx4g/> coment Garbage collector usage <# java.arg.13=-XX:+UseG1GC/>
