Nifi Zookeeper issues with Java 11 and Nifi-1.10.0

Explorer

Hi,

 

I am having issues with the zookeeper (zookeeper-3.4.13) with latest nifi version of Nifi-1.10.0 , below is the stack trace. I am upgrading from nifi-1.9.0 .  let me know if latest version of Nifi needs different version of zookeeper ? or the issue is somewhere else.

 

Not : With Java 8 and nifi-1.9.0 everything works

Re: Nifi Zookeeper issues with Java 11 and Nifi-1.10.0

@samarsimha 

Oh well and good, are you downloading Nifi 1.10.0 from https://nifi.apache.org/download.html  released just last week November 4th, 2019  according to the documentation you  MUST upgrade to zookeeper version 3.5.5  which is the recommended version.

I am sure if you align  zookeeper version to the documentation.

 

Task 6624 is automatic but the 6578 must be done manually 

[NIFI-6624] - Automatically migrate old embedded zookeeper.properties files to the new format

[NIFI-6578] - Upgrade zookeeper to 3.5.5

 

Hope that helps

The simplest answer I can give you if compatibility!  HDF/HDP/HCP are packaged applications that have undergone rigorous unitary tests are supposed to "work as"  that explains why you cannot upgrade ONLY a component and upgrade minor or Major released go through a battery of test and QA to ensure all the components work properly.

In your case Java 7 and 8 are to date the recommended versions the latter being the most preferred.  From the matrix link https://supportmatrix.hortonworks.com/   I filtered out the latest version of HDF and No HDP/HDF product has been certified against Java 11 as of now, that could change in the near future but it won't definitely be with your current version of Nifi  .
Nifi_java11.PNG

 

So the above could explain your dilemma. Do you have a special use case as to why you want to use Java 11? I am not sure whether Cloudera offers a workaround but if you bought support from Cloudera then you can open a ticket.

 

Happy hadooping

Upgrading to Java 11 is a mandate across our ORG. I was able to compile ( On MAC with Java 11) and seems to be working fine. however see above issue when installing Nifi-1.10.0 with external zookeeper.

Task 6624 is automatic but the 6578 must be done manually 

[NIFI-6624] - Automatically migrate old embedded zookeeper.properties files to the new format

[NIFI-6578] - Upgrade zookeeper to 3.5.5

 

Hope that helps
