Question

我想使用以下命令将DataFrame保存为表：

>>> access_df = sqlContext.read.load("hdfs://10.0.0.220/user/nanounanue/access", format="parquet") 
>>> df_writer = pyspark.sql.DataFrameWriter(access_df)
>>> df_writer.saveAsTable('test_access', format='parquet', mode='overwrite')

但是当我尝试最后一行时，我得到了以下stacktrace：

用户nanounanue在该目录中具有写权限：

[hdfs@ip-10-0-0-209 ec2-user]$ hadoop fs -ls -R /user/hive/ | grep warehouse
drwxrwxrwt   - hive hive          0 2015-06-23 21:16 /user/hive/warehouse

缺少什么？

Answer 1

我也遇到过这个问题。当我从Spark 1.2迁移到Spark 1.3时，实际上是权限问题。尝试使用Apache Spark而不是Cloudera，Spark，因为这解决了我的问题。

Answer 2

这似乎是与在Hive元存储目录下创建新目录相关的错误（在您的情况下/user/hive/warehouse）要解决此问题，请尝试changing default permissions为您的元商店目录递归授予您的用户rwx权限。

Answer 3

根据您的日志： file：/ user / hive / warehouse / test_access / _temporary / 0 / _temporary / attempt_201506241321_0001_m_000001_0（exists = false，cwd = file：/ home / nanounanue）

Spark正试图在path / user / hive / warehouse / test_access /

中创建文件

当你使用spark的默认设置时，使用derby作为hivemetastore将导致这个默认的本地路径/ user / hive / warehouse /你的进程没有权限这样做。

Spark 1.4中的saveAsTable无法按预期工作
