Hello @Exor , The issue seems to be that the agent is not able to connect to archive.cloudera.com. Could you check or share what the failure is via the log files present under /tmp/scm_prepare_node.*/*

Hello @khanarshadazmat , We do not have a direct method to get the CM Server and Agent version like we have in java -version. However, you can follow some of the below workarounds to get the required result: 1_). using below command # hdfs version # hadoop version 2_). version info available at "/opt/cloudera/parcels/<CDH>/lib/hadoop/cloudera/cdh_version.properties" Let me know if this helps!

Hello @khanarshadazmat , You may get the role information using CM API for HDFS service. API: https://archive.cloudera.com/cm7/7.2.4/generic/jar/cm_api/apidocs/resource_RolesResource.html#resource_RolesResource_ClustersResourceV43_ServicesResourceV42_RolesResourceV41_readRoles_GET See the below example for a better understanding: • When I execute the above API, I would get the below details for HDFS service: "name" : "HDFS-1-NAMENODE-cb7144bc695976e34cfbaaf26c176d21",
"type" : "NAMENODE",
"serviceRef" : {
"clusterName" : "Cluster 1",
"serviceName" : "HDFS-1",
"serviceDisplayName" : "HDFS-1",
"serviceType" : "HDFS"
}, ...
"roleState" : "STARTED",
"healthSummary" : "GOOD",
"configStalenessStatus" : "FRESH",
"haStatus" : "STANDBY",
"maintenanceMode" : false,
"commissionState" : "COMMISSIONED",
"roleConfigGroupRef" : {
"roleConfigGroupName" : "HDFS-1-NAMENODE-BASE"
}, • and, for the second namenode, I'll get something as below: "name" : "HDFS-1-NAMENODE-b1d777dd6714507397225b07ea9057ce",
"type" : "NAMENODE",
"serviceRef" : {
"clusterName" : "Cluster 1",
"serviceName" : "HDFS-1",
"serviceDisplayName" : "HDFS-1",
"serviceType" : "HDFS"
}, ... "roleState" : "STARTED",
"healthSummary" : "GOOD",
"configStalenessStatus" : "FRESH",
"haStatus" : "ACTIVE",
"maintenanceMode" : false,
"commissionState" : "COMMISSIONED",
"roleConfigGroupRef" : {
"roleConfigGroupName" : "HDFS-1-NAMENODE-BASE"
},
"entityStatus" : "GOOD_HEALTH" • In both the above examples, check for the keyword "haStatus". The namenode with haStatus as Active would be your Active Namenode. Let me know if this helps. Cheers!

Hello @jmbohl , @zuoseven , @napoleon , Please note that this is a known bug, but not yet fixed. Please check if the below properties in CM > HDFS > Configuration is set to an asterisk (*): -------------------------------- HDFS Proxy User Hosts HDFS Proxy User Groups Hue Proxy User Hosts Hue Proxy User Groups -------------------------------- If the above is set to asterisk, please let me know if the below workaround works: 1_). Create the user and group of the HDFS directory in HUE, then log in to HUE with the user of HDFS and then go to HUE to create an ACL for the HDFS directory 2_). Because there is a BUG in HUE for HDFS ACL, it is not recommended to use it this way. It is recommended that you still use the acl command line to create on HDFS. Cheers! Was your question answered?
