Hi , To change the format of the input time we need to use unix_timestamp along with from_unixtime funcitons. Can you check this below Cloudera community article: https://community.cloudera.com/t5/Support-Questions/Format-date-in-HIVE/td-p/203463

Hi, It seems like your host from where you are running Sqoop command is not able to connect on the machine where your mysql is installed. Kindly run the below command to check the connectivity. ## telnet <hostname> 3306 Note:- Hostname is the host where you have installed mysql database. In the sqoop command i can see you have provided "localhost" double check it is the one where mysql database is installed. Below is the command to get the full hostname of the host. ## hostname -f

Hi, Not sure this info is available. 1. you can check the yarn application logs in hdfs under /tmp/logs you can find this exact path by going to Cloudera manager -> Yarn -> Configuration -> yarn.nodemanager.remote-app-log-dir 2. If you have an application id you can just collect the logs manually with below command: ## yarn logs -applicationId <application ID> > applogs.txt

Also should check the output of the query from both hive and Impala, If there is any issues with metadata update after REFRESH we need to check the catalog logs at the same time...

Hi, I am not sure above issue is resolved or not, As per the issue description after REFRESH you are not able to query the table partition in impala but as per the query details you have given i do not see an issue but it just says stats are missing and your query might have succeeded ( I do not know the query status since you haven't given in the details) If partition is not available the query usually fails with "Analysis Exception". If you have such issue you can upload full query profile and its coordinator logs to check the issue.

Hi, These errors are generic errors that can see in the front end and these errors doesn't shows exact issue. Regarding the Error #1: Please check "Setting Up the Kerberos Credential Cache File" for credential cache for windows in the below documentation. https://www.cloudera.com/documentation/other/connectors/impala-odbc/latest/Cloudera-ODBC-Driver-for-Impala-Install-Guide.pdf Also upgrade the ODBC connector to the latest version. Regarding the Error #2: It says "Unexpected response received from server" you need to check the below things to identify the issue: ( Power BI -> ODBC Driver -> LB -> Impala Daemon ) a. Check the ODBC driver logs at the time of issue , If you do not find anything enable trace level logs and check the errors. b. If you have LB configured check the LB logs. c. Try to connect manually for every impala daemon to find out if there is any issue with particular daemon. d. If you faced an issue with connecting any daemon check the logs for more details.

Hi, 1. What is the exact exception from Hue? Is this issue with all users or only specific users? 2. what is the sentry role you mapped to the database? can you check its privileges from below command. ## SHOW GRANT ROLE <role-name> on database <database-name>; 3. check the group that user is belongs to: ## id <username> 4. check if the group is mapped to the sentry role, if not try to map the sentry role to group a user belong to and check the db access. ## GRANT ROLE <role_name> TO GROUP <groupName>;

Hi I think you can try out below two options: 1. Increase idle_session_timeout value in impala 2. Rewrite the script to open Impala connection just before Impala related commands will be invoked.
