Hbase客户端RPC超时 [英] Hbase Client RPC Timeout

问题描述

我正在运行Hbase 1.0.1 / Hadoop 2.5.2。我试图在桌面上运行扫描，但我得到RPC超时。

I'm running Hbase 1.0.1/Hadoop 2.5.2. I'm trying to run a scan on a table but I'm getting RPC timeouts.

我已经将Hbase RPC超时更改为2分钟，我可以确认frm用户界面......

I've changed the Hbase RPC timeout to 2 minutes which I can confirm frm the UI...

<property>
  <name>hbase.rpc.timeout</name>
  <value>120000</value>
  <source>hbase-site.xml</source>
</property>

...但是我的客户仍然在60s后超时......

... but my client is still timing out after 60s...

我试过改变缓存块大小，但是这样做这似乎没有什么区别。

I've tried changing the cache block size but this doesn't seem to make any difference.

是否有其他超时，我错过了。表中有很多行（百万），尽管扫描只返回10的数千行，但问题似乎只与一组特定的区域有关。

Is there some other timeout that I'm missing. There are a lot of rows in the table (millions) although the scan only returns 10's of thousands but the problem only seems to be with a specific set of regions.

推荐答案

在客户端而不是 hbase-site.xml 中创建连接时尝试此操作：

Try this when you create connection in client side instead of in hbase-site.xml:

conf.set("hbase.rpc.timeout", "1800000")
