使用happybase访问HBase出现Broken pipe问题---两个“惊天”大bug

来源
使用happybase通过thrift接口向HBase读取、写入数据时，出现Broken pipe的错误。排查步骤：

1、查看hbase的日志：

初步推断是hbase设置了某个超时时间，导致连接断开

2、查看官方文档，但是没有发现很有意义的timeout参数

3、Google相似问题

Release Note: Adds a timeout to server read from clients. Adds new configs hbase.thrift.server.socket.read.timeout for setting read timeout on server socket in milliseconds. Default is 60000;

Thrift server is hung. All worker threads are doing this:

They never recover.
I don't have client side logs.
We've been here before: HBASE-4967 "connected client thrift sockets should have a server side read timeout" but this patch only got applied to fb branch (and thrift has changed since then)
ps：来源https://issues.apache.org/jira/browse/HBASE-14926

4、Google “hbase.thrift.server.socket.read.timeout”

可以看到一个网页内容：

问题背景

测试环境是三台服务器搭建的Hadoop分布式环境。Hadoop版本是：hadoop-2.7.3；Hbase-1.2.4； 
zookeeper-3.4.9。 
使用thrift c++接口向hbase中写入数据，每次都是刚开始写入正常，过一段时间就开始报错。 
但之前使用的hbase-0.94.27版本就没遇到过该问题，配置也相同，一直用的好好地。

thrift接口报错

解决办法

通过抓包可以看出，hbase server响应了RST包，导致连接中断。 
通过 bin/hbase thrift start -threadpool命令可以readTimeout的设置为60s。

thriftpool

经过验证却是和这个设置有关，配置中没有配置过该项，通过查看代码发现60s是默认值，如果没有配置即按照以该值为准。

因此在conf/hbase-site.xml中添加上配置即可：

<property>
         <name>hbase.thrift.server.socket.read.timeout</name>
         <value>6000000</value>
         <description>eg:milisecond</description>
</property>

ps：来源http://blog.csdn.net/wwlhz/article/details/56012053

所以添加参数后，重启hbase thrift，发现问题解决

5、查看源码，可以看到

#https://github.com/apache/hbase/blob/master/hbase-thrift/src/main/java/org/apache/hadoop/hbase/thrift/ThriftServerRunner.java

...
  public static final String THRIFT_SERVER_SOCKET_READ_TIMEOUT_KEY =
    "hbase.thrift.server.socket.read.timeout";
  public static final int THRIFT_SERVER_SOCKET_READ_TIMEOUT_DEFAULT = 60000;
.
.
.
      int readTimeout = conf.getInt(THRIFT_SERVER_SOCKET_READ_TIMEOUT_KEY,
          THRIFT_SERVER_SOCKET_READ_TIMEOUT_DEFAULT);
      TServerTransport serverTransport = new TServerSocket(
          new TServerSocket.ServerSocketTransportArgs().
              bindAddr(new InetSocketAddress(listenAddress, listenPort)).
              backlog(backlog).
              clientTimeout(readTimeout));

问题解决~~~

6、然而问题解决了吗？

实际上还是有问题，一段时间发现连续scan大概20多分钟后，连接又被断开了，又是一次艰难的搜索，发现是hbase该版本自带的问题，它将所有连接（不管有没有在使用）都默认为idle的状态，然后有个hbase.thrift.connection.max-idletime的配置，所以我将此项配置为31104000（一年），如果是在CDH中，应该在管理页面配置，如图：

遇到问题一般步骤：
技术进步型：
1、查看日志，查看报错的地方，初步定位问题
2、查看官方文档
3、Google相似的问题，或者查看源码去定位问题
