hi all the following link is a great info to know versions that supported https://supportmatrix.hortonworks.com/ but how to know the kafka version of each HDP version? second lets take the HDP version - 3.1 can we compare the kafka version that contain in HDP 3.1 to kafka confluent version ? one of the problems is that kafka confluent latest version is much higher then the kafka version in HDP 3.1 why this Gap ?

hi all how to download the zookeeper server pkgs by wget from hortonworks repository ( HDP 2.6.4 )

mike_bronson7 · ‎06-27-2019

hi all We are using the hortonworks kits for our hadoop cluster ( HDP - 2.6.4 - HDP 3.1 ) I just wondering if any of kafka versions in HDP 2.X / 3.X must have a zookeeper servers?? Or maybe some kafka version can works without zookeeper??

mike_bronson7 · ‎06-27-2019

we have HDP version 2.6.4 in our cluster cluster include 285 data node machines and 3 kafka machines for now zookeeper servers are installed on the masters machines and zookeepers are not independent machines but since this is very important production cluster we think to separate the zookeeper from the masters machines and install the zookeeper servers on separate servers to be independent machines am I right here?

hi all we download the HDP packages from HDP 2.6.4 version and we want to installed only a new 3 zookeeper servers on new machines ( without ambari ) how to exclude the zookeeper packages from the HDP 2.6.4 kit so we can install only the zookeeper servers on the new machines

hi all we saw a millions WARN message from zookeeper log 2019-06-26 04:07:06,459 [myid:2] - WARN [NIOServerCxn.Factory 0.000.0.0/0.0.0.0:2181:NIOServerCnxn@357] - caught end of stream exception EndOfStreamException: Unable to read additional data from client sessionid 0x26b8e150308cd3c, likely client has closed socket at org.apache.zookeeper.server.NIOServerCnxn.doIO(NIOServerCnxn.java:230) at org.apache.zookeeper.server.NIOServerCnxnFactory.run(NIOServerCnxnFactory.java:208) at java.lang.Thread.run(Thread.java:745) what is the meaning of this warning ?

hi all can you upgrade HDP 2.6.4 to 3.1 and stay with ambari 2.6.1?

mike_bronson7 · ‎06-17-2019

second when I saved the parameter in ambari - Ambari -> HDFS -> Configs -> Advanced -> Custom hdfs-site dfs.namenode.fs-limits.max-directory-items=2097152 I GET: The configuration changes could not be validated for consistency due to an unknown error. Your changes have not been saved yet. Would you like to proceed and save the changes? dose this parameter supported in HDP version - 2.6.4?

mike_bronson7 · ‎06-17-2019

@Geoffrey Shelton Okot - do you mean to restart the ambari server ? as ambari server restart? instead to restart the HDFS and YARN services ? ( after we set dfs.namenode.fs-limits.max-directory-items )
