hi @huimin, what error is being returned when accessing HDFS using Trino? i recommend investigating the namenode logs and even the Trino logs to verify the error details.

hi @Boris G, example of an error collected in the impalad log: E0731 04:30:49.177050 59498 authentication.cc:164] SASL message (Kerberos (external)): GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Clock skew too great) error when trying to connect to impalad with impala-shell: Error connecting: TTransportException, TSocket read 0 bytes Researching this error (Clock skew too great), it's something related to NTP synchronization, but the NTP service is synchronized with KDC (AD), as shown in the chronyd tracking command: Ref time (UTC): Thu Jul 31 12:25:09 2025 Date command: Thu Jul 31 09:25:14 -03 2025 PS: My timezone is -3.

hi @Boris G, we believe the problem is with Impala and not Hue, as the same error is occurring when trying to connect directly to the Impala daemon host with Impala-shell.

hi @Malrashed, we do not use swap on Cloudera cluster hosts. we disable 100% or keep the value 1 in the vm.swappiness parameter. reference: https://docs.cloudera.com/cdp-reference-architectures/latest/cdp-pvc-base-ra/topics/ra-cdpdc-swapiness.html best regards 🙂

hi @RamaClouder, current scenario: You're running CDP in the cloud, using the CDP Public Cloud, right? if so, you have technical support included with your license. For more accurate and responsive support, we recommend opening a case in the "My Cloudera" portal as S1, and support will assist you as soon as possible. if not, please return with the stderr and stdout logs for more details. tip: Check permission settings in IAM, broker, etc.

hi @Malrashed , did you completely disable swap at the operating system level? comment out the swap line in the fstab file. run the swap off command. the free command returns swap 0 (zero). after disabling, did you restart the Cloudera agent?

hi community cloudera, recently, we've been receiving the following error when querying impala on hue: queryerror: tsocket read 0 bytes (code thrifttransport): ttransportexception('tsocket read 0 bytes',) - the "query_timeout_s" and "session_timeout_s" parameters have already been set to 2 hours in the hue settings. - the hs2 and impala thrift connection timeout has already been set to 2 hours in the hue settings. - the hs2 authentication timeout has already been set to kerberos in the hue settings. - the "proxytimeout" parameter has already been set to 10 minutes in the hue settings. and we're still receiving this error. has anyone experienced this issue and managed to resolve it? we're using cdh 6.3.4.

hi @vineetchaure, the Cloudera Manager itself manages the service startup scripts. we do not recommend modifying the Cloudera service startup scripts, as this will harm and interfere with correct startup and consequently generate unwanted problems.
