如何在拆分Solr的云Solr的碎片 [英] How to Split solr shard in solr cloud

问题描述

我使用Solr的4.10.3在solrCloud模式。我有一个碎片和3个复本。外部动物园管理员在合奏中使用。我在一个索引文件已经增加太多。现在我想创造更多的碎片。我尝试使用

<$p$p><$c$c>http://localhost:8983/solr/admin/collections?action=SPLITSHARD&collection=collection1&shard=shard1

但它提供了以下错误

 收集错误执行拆分操作：collection1父碎片：shard1
显示java.lang.NullPointerException
    在org.apache.solr.cloud.OverseerCollectionProcessor.splitShard（OverseerCollectionProcessor.java:1288）

问题出在哪里，什么是它的soultion？

解决方案

当你已经定义-DnumShards酒店SPLITSHARD只能用于=（某个值），当您启动集群第一次。

I am using solr 4.10.3 in solrCloud mode. I have one shard and 3 replica. external zookeeper ensemble in being used. My document in one index has been increase too much. Now I want to create more shards. I tries to use

http://localhost:8983/solr/admin/collections?action=SPLITSHARD&collection=collection1&shard=shard1

But it gives following error

Error executing split operation for collection: collection1 parent shard: shard1

Where is the problem and what is its soultion?

解决方案

The property SPLITSHARD can only be used when you have defined -DnumShards=(some value) when you start you cluster first time.
