Hello @md186036 ,   I have checked the Navigator logs in a test cluster for CDH5.16 (for our purposes this minor version difference should not matter much) and found the entries mentioned in this doc for CDH5.15: 2020-07-29 17:41:18,151 INFO com.cloudera.nav.server.NavServerUtil [main]: Found 885 documents in solr core nav_elements 2020-07-29 17:41:18,155 INFO com.cloudera.nav.server.NavServerUtil [main]: Found 916 documents in solr core nav_relations   I was navigating in CM -> Cloudera Management Service -> Navigator Metadata Server and then clicked on Log Files -> Role log file. I have downloaded the file by clicking on the "Download Full Log". I have observed that I have log entries saying INFO messages.   Do you see log entries with INFO in the log too, please? I would like to rule out that the log level was not applied since your config change (e.g. was not restarted) or the log level was changed in other means (e.g. without restart).   Thank you: Ferenc ...

Hello @meiravR ,   thank you for asking for clarification. I was just wondering if e.g. between step 3. and 5. you pasted the data somewhere (e.g. to a notebook, an editor, a text file, a chat window, a google doc, an MS Word editor) and then copied it out again?   Thank you: Ferenc ... View more

Hello @md186036 ,   do you see INFO level messages in the prod cluster log? I am suspecting that your log level is set to e.g. WARN or ERROR level/threshold and maybe this is the reason you do not see the "nav_" elements. It can be set via CM's service configuration too   Thank you: Ferenc ... View more

Hello @md186036 ,   thank you for your questions on How to disable heap dump, so your tmp folder is not filling up on OOM How to calculate the optimal heap size for Navigator Metadata Server if you cannot locate the nav_elements and nav_locations pattern in cloudera-scm-navigator log file   In CM -> Cloudera Management Service -> Configuration -> Category: Advanced -> Uncheck "Dump Heap When Out of Memory" To assist you more efficiently, can you please specify the CDH version you are using, please?   Thank you: Ferenc ...

Hello @meiravR ,   thank you for reporting your experience having difficulty adding a new environment to the CDP public cloud.   During the process of creating CDP credential, we need to copy and paste texts that contain special characters. Just to narrow down the possible cause of the issue, can you please confirm if you used any text editor to paste these values (e.g. for documentation purposes) and copied it back to the browser? I would like to rule out the possibility that encodings changed between copying and pasting, hence the characters displayed represented some other characters (that might be not obvious to differentiate visually, e.g. control characters are not displayed).   Do you face the same issue when you are using only a plain character-based editor to save your work, please?   Thank you: Ferenc ...

Hello @agsumeet , @direcision , @Dorown and @abinanths ,   thank you for reaching out! I have checked internally and the issue described in this thread looks like HIVE-16683 / SPARK-26932   As of now, there is no fix backported to any CDH release (at the time of writing it means CDH6.3.3 and earlier).   Should you have a Cloudera Support Subscription, please file a support case with us for further assistance!   Thank you: Ferenc ...

Hello @Pr1 ,   thank you for your enquiries about Graphql API access via REST and NiFi REST interactions.   Found this article about GraphQL via REST and the NiFi REST API Reference documentation.   Have you seen these already?   Thank you: Ferenc   ... View more

Hello @AdityaShaw ,   sorry I have missed addressing your enquiry about the server 500 error. Based on the KB article you referenced, it is related to the bug. Do you still have the server 500 error once hive.server2.thrift.http.cookie.auth.enabled is set to false, please?   Should you experience disconnects even after applying the workaround, you might have too many HTTPClient connections, which are too high for KNOX to handle at a time.   Please only change any of the parameters listed below once you tested that the above workaround was not sufficient. Based on my research the below parameters are still safe to apply. Before applying any changes in production, please test out the new values in a non-prod environment, as we are not familiar with your use cases and how your cluster/workload is designed: gateway.httpclient.connectionTimeout=600000 (10 min) gateway.httpclient.socketTimeout=600000 (10 min) gateway.metrics.enabled=false gateway.jmx.metrics.reporting.enabled=false gateway.httpclient.maxConnections=128   Kind regards: Ferenc   ...
