hive常見異常

1.Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.MoveTask. org.apache.hadoop.hive.ql.metadata.HiveException: Unable to move source file:

解決：
退出hive，關閉namenode和datanode，刪除namenode的tmp目錄，再重新啓動

2.多表查詢有聚合函數執行mapreduce出錯：

FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask MapReduce Jobs Launched:

待解決：
hive> set hive.exec.mode.local.auto=true;

3.啓動hive後，第二次同樣的select語句會出錯。
FAILED: Hive Internal Error: java.lang.IllegalArgumentException(The value of property yarn.resourcemanager.zk-address must not be null) java.lang.IllegalArgumentException: The value of property yarn.resourcemanager.zk-address must not be null

解決：
把yarn-site.xml中的yarn.resourcemanager.zk-address改爲hadoop.zk.address
並重啓hadoop。

4.cannot recognize input near ‘date’ ‘string’ ‘,’ in column specification

解決：
date爲保留關鍵字，當字段名與關鍵字重名時。要加上反引號

5.Error: Could not open client transport with JDBC Uri: jdbc:hive2://192.168.1.101:10000: Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: leon is not allowed to impersonate leon (state=08S01,code=0)

解決：
修改core-site.xml文件添加如下：

<property>
    <name>hadoop.proxyuser.leon.hosts</name>
    <value>*</value>
</property>
<property>
    <name>hadoop.proxyuser.leon.groups</name>
    <value>*</value>
</property>

注意：hadoop.proxyuser.leon.hosts和hadoop.proxyuser.leon.groups中的leon是我的用戶名，你要改成你的用戶名
