嗨,我在一个大表上运行phoenix count查询时收到下面的错误消息。

0: jdbc:phoenix:hadoopm1:2181> select Count(*) from PJM_DATASET;
+------------+
|  COUNT(1)  |
+------------+

java.lang.RuntimeException: org.apache.phoenix.exception.PhoenixIOException: org.apache.phoenix.exception.PhoenixIOException: Failed after attempts=36, exceptions:

请帮忙。

我们今天遇到了非常类似的例外:

java.net.SocketTimeoutException: callTimeout=60000, callDuration=60101: row '' on table '****' at region=****, hostname=wn1-bghbas.y1ao3ht4safu3e4em4fhuri0eh.ax.internal.cloudapp.net,16020,1543844388080, seqNum=568644

       ... 11 more

在跟踪异常的调用跟踪之后,我们发现正确的配置变量是 hbase.client.scanner.timeout.period . 可以在课堂上找到 org.apache.hadoop.hbase.HConstants 以他的名义 HBASE_CLIENT_SCANNER_TIMEOUT_PERIOD .
请注意,如果要传递 hbase.client.scanner.timeout.period 作为财产 PhoenixDriver 使用原始jdbc,值必须 String ,不是 int .
比如:

Properties prop = new Properties();
prop.put("user", "***");
prop.put("password", "***");
prop.put(HConstants.HBASE_CLIENT_SCANNER_TIMEOUT_PERIOD, "800000");
Connection connection = DriverManager.getConnection("jdbc:phoenix:10.0.0.1:2181:/hbase-unsecure", prop);

作为记录,我们在hbase 1.1上使用phoenix 4.7

您需要在hbase服务器和客户端配置中将下面的hbase配置属性增加到更高的值,默认值为1分钟(60000毫秒)

<property>
    <name>hbase.rpc.timeout</name>
    <value>600000</value>
  </property>

最重要的是,下面的命令应该返回正确的hbase config目录,其中hbase-site.xml文件包含上述属性。如果hbase\u conf\u path的值为空或,则执行命令 export HADOOP_CONF_DIR=<correct_hbase_dir>; 用于在执行命令之前指向正确的hbase配置 sqlline.py .

phoenix_utils.py  | grep hbase_conf_path

calltimeout=60000,callduration=62365。
看起来您的通话持续时间超过10分钟,这是超时持续时间。尝试将hbase-default.xml(或您的自定义)配置文件中的“hbase.master.catalog.timeout”设置为更高的值
