问题 Currently, I have zknodes with ACL property world:anyone:crdwa. With new requirement, I need to update ACL to use auth scheme. For that, I need to update all current zknodes with auth scheme ACL too. I am planning to write a python script and do DFS traversal doing so. I want to reach out to learn, if there is an open source library or better way to achieve the same? 回答1: Scripting the traversal in Python (or any language of choice) is a viable solution.

问题 I am trying to setup HBase in a fully distributed mode: consisting of 1 master and 2 region servers. I have set HBASE_MANAGES_ZK = true in hbase-env.sh. The hadoop cluster is running on the cluster with following configurations: Master: node-master Regionserver1: node1 Regionserver2: node2 When I am starting HBase, I can see that RegionServers are getting started and HQuorumPeer on master also, but HMaster is not showing. Please find the logs as below: Master hbase-site.xml <configuration>

问题 Currently I have a standalone ZK instances used in a test system. But this test system has become production system and i would like to upgrade from 1 ZK instance to 3 without compromising availability of the SolrCloud system that ZK is overseeing. From what i've read upgrading from 3 to 5 and so on is pretty easy using rolling restarts, but haven't found any info on going from standalone (1 instance) to 3. Does anyone have any insight on this (anyone who might have tried it)? Thanks! 回答1: I

问题 I was trying out hbase spark distributed scan example.

问题 In Production environment, should Solr be setup on every server possible including the one having Zookeeper? Talking about External Zookeeper Total Servers : 5 Case 1: Solr on all 5 servers. Zookeeper on 3 servers. Case 2: Solr on 2 servers. Zookeeper on 3 servers. Case 3: Solr on 5 servers. Zookeeper on 5 servers. What is the best practice? What are the advantages of using one case over another? I have read that it's better to have Zookeeper in a separate server. 回答1: At any point of time

问题 I have Kafka Stream application. My application is processing the events successfully. How to change Kafka committed consumer offset with required offset to reprocess/skip the events. I tried How to change start offset for topic?. But I got 'Node does not exist:' error. Please help me. 回答1: The question/answer you are referring to is based on an older Kafka version.

问题 I'm using the official stable ZooKeeper Helm chart for Kubernetes which pulls a ZooKeeper Docker image from Google's sample images on Google Container Registry. That ZooKeeper image is available here, however, I can't seem to find any reference to the Dockerfile for how it is built or if its Dockerfile is generated from some other representation (e.g., via Bazel). I'd like to know info like what else is installed on the image, what OS it's based on, etc. In general are Dockerfiles for the
