Abhilash Perla updated KNOX-2709: --------------------------------- Description: When validating retry parameters (maxRetryAttempts , retrySleep) in Knox HA provider observed that no retries are taking place for webhdfs when Namenode is in safemode while in documentation it says the retry should take place for this case ( Doc link : [https://knox.apache.org/books/knox-1-1-0/user-guide.html#WebHDFS+HA] ) According to this Jira: https://issues.apache.org/jira/browse/KNOX-1093 There should be no retry parameters for webhdfs api in safe mode. So the documentation should be updated. was: When validating retry parameters (maxRetryAttempts , retrySleep) in Knox HA provider observed that no retries are taking place for webhdfs when Namenode is in safemode while in documentation it says the retry should take place for this case ( Doc link : [https://knox.apache.org/books/knox-1-1-0/user-guide.html#WebHDFS+HA] ) Observed only failover is happening in this case *Steps taken:* 1. Turned on safe mode for Hdfs 2. Did a curl put request through webhdfs api. *Executed command:* curl -i -k -u knoxui:knoxui -X PUT '[https://quasar-zyumtb-1.quasar-zyumtb.root.hwx.site:8443/gateway/cdp-proxy-api/webhdfs/v1/user/guest/example/README1?op=CREATE'|https://quasar-zyumtb-1.quasar-zyumtb.root.hwx.site:8443/gateway/cdp-proxy-api/webhdfs/v1/user/guest/example/README1?op=CREATE%27] The output in Knox/gateway/gateway.log: !image-2022-02-24-19-59-38-998.png! The output in gateway-audit.log: !image-2022-02-24-20-00-10-074.png! The topology configurations(Snippet from cdp-proxy-api.xml): !image-2022-02-24-20-01-26-352.png|width=603,height=42! *Expected Output:* Retry should happen 300 times with interval between each retry should be 1second *Actual Output:* In the above case failover attempts is set to 6 . So 6 times failover happened but retry is not happening. Note: Added the Topology and log files of both instances in attachments > Retry is not happening for webhdfs api in Knox HA provider > ---------------------------------------------------------- > > Key: KNOX-2709 > URL: https://issues.apache.org/jira/browse/KNOX-2709 > Project: Apache Knox > Issue Type: Bug > Reporter: Abhilash Perla > Priority: Major > > When validating retry parameters (maxRetryAttempts , retrySleep) in Knox HA > provider observed that no retries are taking place for webhdfs when Namenode > is in safemode while in documentation it says the retry should take place for > this case ( Doc link : > [https://knox.apache.org/books/knox-1-1-0/user-guide.html#WebHDFS+HA] ) > According to this Jira: https://issues.apache.org/jira/browse/KNOX-1093 > There should be no retry parameters for webhdfs api in safe mode. > So the documentation should be updated. > > -- This message was sent by Atlassian Jira (v8.20.1#820001)
