Question

Hive版本：0.13.1

猪版：0.13.0

我试图用以下命令使用pig读取蜂巢表。

grunt> DATA = LOAD 'dev.profile' USING org.apache.hcatalog.pig.HCatLoader();

我得到下面的日志

2014-07-16 22:44:58,986 [main] WARN  org.apache.hadoop.hive.conf.HiveConf - DEPRECATED: hive.metastore.ds.retry.* no longer has any effect.  Use hive.hmshandler.retry.* instead
2014-07-16 22:44:59,037 [main] INFO  hive.metastore - Trying to connect to metastore with URI thrift://localhost:10000
2014-07-16 22:44:59,057 [main] INFO  hive.metastore - Connected to metastore.
2014-07-16 22:45:02,019 [main] WARN  org.apache.hadoop.hive.conf.HiveConf - DEPRECATED: hive.metastore.ds.retry.* no longer has any effect.  Use hive.hmshandler.retry.* instead

当我进行描述时，结果会按预期正确显示。

grunt> describe DATA
2014-07-16 22:46:42,189 [main] WARN  org.apache.hadoop.hive.conf.HiveConf - DEPRECATED: hive.metastore.ds.retry.* no longer has any effect.  Use hive.hmshandler.retry.* instead
DATA: {name: chararray,age: int,salary: int}

但是当我转储数据时，我得到SocketTimeoutException

即使我能够连接到Metastore，我也无法检索数据。读取失败的原因是什么？有时，进程因java.lang.OutOfMemoryError：Java堆空间

而失败

非常感谢任何帮助。

编辑hive-site.xml。将hive.metastore.ds.retry替换为/hive.hmshandler.retry。

vim /usr/local/Cellar/hive/0.13.1/libexec/conf/hive-site.xml
:%s/hive.metastore.ds.retry/hive.hmshandler.retry/g
:wq

apache thrift transport TTransportException
