我正在尝试在 BigInsights on Cloud 4.2 Enterprise 上运行访问 Hive 表的 pyspark 脚本。

首先，我创建 hive 表：

[biadmin@bi4c-xxxxx-mastermanager ~]$ hive
hive> CREATE TABLE pokes (foo INT, bar STRING);
OK
Time taken: 2.147 seconds
hive> LOAD DATA LOCAL INPATH '/usr/iop/4.2.0.0/hive/doc/examples/files/kv1.txt' OVERWRITE INTO TABLE pokes;
Loading data to table default.pokes
Table default.pokes stats: [numFiles=1, numRows=0, totalSize=5812, rawDataSize=0]
OK
Time taken: 0.49 seconds
hive>

然后我创建一个简单的 pyspark 脚本：

[biadmin@bi4c-xxxxxx-mastermanager ~]$ cat test_pokes.py
from pyspark import SparkContext

sc = SparkContext()

from pyspark.sql import HiveContext
hc = HiveContext(sc)

pokesRdd = hc.sql('select * from pokes')
print( pokesRdd.collect() )

我尝试执行：

spark-submit --master yarn-cluster test_pokes.py

但是，我遇到错误：

You must build Spark with Hive. Export 'SPARK_HIVE=true' and run build/sbt assembly
Traceback (most recent call last):
  File "test_pokes.py", line 8, in <module>
    pokesRdd = hc.sql('select * from pokes')

我已经看到许多其他 Hadoop 发行版的类似帖子，但没有看到 BigInsights on Cloud。

此错误的解决方案是添加罐子：

[biadmin@bi4c-xxxxxx-mastermanager ~]$ spark-submit \
    --master yarn-cluster \
    --deploy-mode cluster \
    --jars /usr/iop/4.2.0.0/hive/lib/datanucleus-api-jdo-3.2.6.jar, \
           /usr/iop/4.2.0.0/hive/lib/datanucleus-core-3.2.10.jar, \
           /usr/iop/4.2.0.0/hive/lib/datanucleus-rdbms-3.2.9.jar \
    test_pokes.py

但是，然后我得到一个不同的错误：

pyspark.sql.utils.AnalysisException: u'Table not found: pokes; line 1 pos 14'

我在这里添加了另一个问题：Spark Hive 报告 pyspark.sql.utils.AnalysisException: u'Table not found: XXX' when run on yarn cluster
