我在Hive Query上执行连接时遇到以下异常,并且在68%完成后,reducer挂起。
java.lang.RuntimeException: org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error while processing row (tag=1) {"key":{"joinkey0":"12"},"value":{"_col2":"rs317647905"},"alias":1}

以下是我的查询和表格结构:
create table table_llv_N_C as select table_line_n_passed.chromosome_number,table_line_n_passed.position,table_line_c_passed.id from table_line_n_passed join table_line_c_passed on (table_line_n_passed.chromosome_number=table_line_c_passed.chromosome_number)
hive> desc table_line_n_passed;
OK
chromosome_number string
position int
id string
ref string
alt string
quality double
filter string
info string
format string
line6 string
Time taken: 0.854 seconds
为什么我会收到此错误,我该如何解决? 下面给出了完整的堆栈跟踪。

答案 0 :(得分:2)
根本原因可能是HDFS集群中缺少磁盘空间,这是因为查询似乎仅在运行一段时间后才会失败并与堆栈跟踪中的此消息结合使用:
... could only be replicated to 0 nodes instead of minReplication (=1). There are 2 datanode(s) running and no node(s) are excluded in this operation.
当存在网络通信问题(例如,与数据节点失去通信)或者HDFS无法为写操作提供服务时,该消息似乎就会出现,因为没有可以找到带有空闲块的数据节点。由于您的查询成功启动,因此我倾向于排除网络问题;相反,您的Hive查询似乎没有尝试生成该表的磁盘空间。您可能需要检查群集上的当前使用情况,这可以通过Ambari(如果您已安装)等方式完成,或者通过命令行执行以下操作之一:
hdfs dfs -df -h
如果您正在运行旧版本,则可能类似于:
hadoop fs -df -h
