ambari metrics collector not display the metrics after moving to distributed mode

mike_bronson7 — Thu, 20 Feb 2020 21:29:14 GMT

hi all

we have HDP version 2.6.5 and ambari 2.6.2.2

we configured the following

Metrics Service operation mode=distributed

hbase.rootdir=hdfs://hdfsha:8020/user/ams/hbase

and all the rest according to - https://cwiki.apache.org/confluence/display/AMBARI/AMS+-+distributed+mode

so ambari configured to save the data on hdfs instead the local disk

after metrics collector service restart we saw the following from log

2020-02-20 20:09:15,770 INFO [timeline] timeline.HadoopTimelineMetricsSink: No live collector to send metrics to. Metrics to be sent will be discarded. This message will be skipped for the next 20 times.
2020-02-20 20:11:35,769 INFO [timeline] timeline.HadoopTimelineMetricsSink: No live collector to send metrics to. Metrics to be sent will be discarded. This message will be skipped for the next 20 times.

and

2020-02-20 20:30:10,306 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: phoenix metrics system started
2020-02-20 20:30:10,450 WARN org.apache.hadoop.hbase.io.util.HeapMemorySizeUtil: hbase.regionserver.global.memstore.upperLimit is deprecated by hbase.regionserver.global.memstore.size

and without metrics as

and after some time the metrics collector service failed

why this happens ?

NOTE - I must to say that - when data of metrics saved on local disk then everything was ok

is that because reaching data on HDFS is more slow?

@mike_bronson7

This does not look right? Ideally with HDFS HA name we do not use the Port number because "hdfsha" is not a hostname but just a logical name.

hbase.rootdir=hdfs://hdfsha:8020/user/ams/hbase

If you NameService name is "hdfsha" (defined in "Custom core-site" as "dfs.nameservices=hdfsha") then ideally you should be using the following in your AMS configuration in your "Advanced ams-hbase-site"

hbase.rootdir=/user/ams/hbase

. As your AMS mode is "distributed" hence AMS will automatically assume that the data is in HDFS and will be able to figure out the actual NameService name dynamically so we do not even need to specify "hdfs://hdfsha" there. After fixing the "hbase.rootdir" in AMS configs please kill and restart the AMS processes. Then specially check the AMS logs specially the following logs and please share if you notice any error ... please share the Full stacktrace.

Dear jay

do you mean to set it as

Re: ambari metrics collector not display the metrics after moving to distributed mode

jsensharma — Fri, 21 Feb 2020 03:29:28 GMT

@mike_bronson7

As the Metrics Service operation mode is already selected to "distributed" hence Ambari will make AMS aware that it needs to find that hbase.rootdir on HDFS.
Following should be fine.

hbase.rootdir=/user/ams/hbase

we configured the following

this are the logs ( still metrics are now shown from ambari , and we have the same alert on the metrics service )

Re: ambari metrics collector not display the metrics after moving to distributed mode

jsensharma — Fri, 21 Feb 2020 04:29:41 GMT

@mike_bronson7

As we see the error as: "Table Namespace Manager not fully initialized"

Which indicates the AMS HBase master might have some issue. Can you please let us know when was "distributed Mode" AMS running fine last time? Or immediately after enabling AMS distributed mode it is not starting?

Is it kerberos enabled environment?

Can you please check the permission on the HDFS dir? (to verify if the ownership of this HDFS dir is setup correctly as "ams:hdfs")

# su - hdfs -c 'hdfs dfs -ls /user/ams' # su - hdfs -c 'hdfs dfs -ls /user/ams/hbase'

If you still face any issue then may be you can try to change the Zookeeper ZNode for AMS and then try restarting AMS freshly.
To change the "Zookeeper Znode Parent" property of AMS please try this.

Ambari UI --> Amabri Metrics --> Configs --> "Advanced ams-hbase-site" --> "ZooKeeper Znode Parent"

then change the value of the znode to something slightly different like "/ams-hbase-unsecure" to "/ams-hbase-unsecure1" ...etc and restart AMS and let us know if you see any error?

Re: ambari metrics collector not display the metrics after moving to distributed mode

mike_bronson7 — Fri, 21 Feb 2020 06:58:14 GMT

Dear Jay

yes change the ams-hbase-unsecure1 is part of the solution , also I increase the heap size since we saw also error about the heap size

I will build more new cluster with your correction , and I will let you know if metrics working fine with

hbase.rootdir=/user/ams/hbase

regarding this ambari cluster , I noticed that some of the metrics are shown and some of them are not
