我可以用命令行运行pig脚本

pig -useHCatalog

但在运行oozie工作流时，pig操作无法运行，出现错误：

ERROR 2244: Job failed, hadoop does not return any error message
ERROR 2245: Cannot get schema from loadFunc org.apache.hive.hcatalog.pig.HCatLoader

INFO conf.HiveConf: Found configuration file null
INFO common.HiveClientCache: Initializing cache: eviction-timeout=120 initial-capacity=50 maximum-capacity=50

ERROR metastore.RetryingHMSHandler: java.lang.NoClassDefFoundError: org/datanucleus/NucleusContext

Not able to connect hive.metastore after giving path of hive-site.xml

如何使用 -useHCatalog 在 oozie 工作流 Pig 行动？
