问题 I am having an interesting situation with SolrCloud. Basically, I dont know why, but Solr instance, which does not in the cloud normally, is displayed on SolrCloud page and also visible in live_nodes path in Zookepeer. Here are details about the situation: I have one Solr instance, running as a standalone application on a virtual machine, located on a remove machine. We will call it virtual1 from now on. This is the script for running it: java -server -XX:+UnlockExperimentalVMOptions -XX:

问题 I have a situation where Zookeeper is configured for 2 nodes but at times it starts running on both the nodes simultaneously. Why this might be happening? 回答1: To make an ensemble with Master-slave architecture you need to have odd number of zookeeper server .i.e.{1, 3 ,5,7....etc}. Ensemble of 3 can handle the one server crash ..similarly ensemble of 5 can handle 2 server ...so on . When you are trying to create an ensemble of 2 servers ,zookeeper actually cannot understand this an ensemble

问题 I am trying to run the SimpleShortestPathsVertex (aka SimpleShortestPathComputation) example described in the Giraph Quick Start.

问题 Currently I have a zookeeper instance controlling replication on 3 physical servers. It is the solr integrated zookeeper. 1 shard, 1 collection. I have a new requirement in which I will need a new static solr instance (1 new collection, no replication). Same schema as previous collection. A copy of this instance will also be placed on the 3 physical servers mentioned above. A caveat is that I need to perform distributed searches across the 2 collections and have the results blended. Thanks to

问题 I am working on java interface which would take user input of topic name, replication and partition to create a kafka topic in KAFKA-2.1.1-1.2.1.1.

问题 There is a problem that bothers me. EndOfStreamExceptionalways happen in zookeeper after submitted topologies. Although it does not affect the normal operation of the cluster, I still hope to solve the problem because it may be affect other parts of Heron function.

The contents of zoo.cfg are as follows. tickTime=10000 initLimit=100 syncLimit=50 dataDir=/home/yitian/zookeeper/data dataLogDir=/home
