配置单元版本:0.13.1
清管器版本:0.13.0
我试着用pig和下面的命令来读取Hive表。
grunt> DATA = LOAD 'dev.profile' USING org.apache.hcatalog.pig.HCatLoader();
我得到下面那块木头
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

当我描述的结果来正确的预期。
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,我得到了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?有时进程会失败,返回java.lang.outofmemoryerror:java堆空间
任何帮助都将不胜感激。

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