SPARK：无法实例化org.apache.hadoop.hive.metastore.HiveMetaStoreClient

标签： hadoop hive apache-spark

我正在运行Hadoop 2.7.0，hive 1.1.0和spark 1.3.1。我在mysql数据库中有我的Metastore数据库。我可以从hive shell创建和查看数据。

hive (dwhdb)> select * from dwhdb.test_sample;
OK
test_sample.emp_id	test_sample.emp_name	test_sample.emp_dept	test_sample.emp_sal
Eid1	EName1	EDept1	100.0
Eid2	EName2	EDept1	102.0
Eid3	EName3	EDept1	101.0
Eid4	EName4	EDept2	110.0
Eid5	EName5	EDept2	121.0
Eid6	EName6	EDept3	99.0
Time taken: 0.135 seconds, Fetched: 6 row(s)

但是当我试图从火花中选择相同的数据时，我收到了错误

请您告诉我可能的原因是什么。

1 个答案:

答案 0 :(得分：0)

日志显示您正在尝试转换字符串＆＃39; 600s＆＃39;到整数。你能检查一下你在哪里提供这个。看起来你在你的hive-site.xml中有这个。 请将其更改为＆＃39; 600＆＃39;。
