我正在尝试将我的胶水目录连接到EMR中的Presto和Hive。在presto cli中运行查询时,我得到了nullpointerException,但是
相同的查询在hive cli中成功。
如下所示启动了CLI
presto-cli --catalog hive
执行查询时出现异常:
Query 20180814_174636_00003_iika5 failed: java.lang.NullPointerException: parameters is null
EMR配置如下:
[
{
"classification": "presto-connector-hive",
"properties": {
"hive.metastore": "glue"
},
"configurations": []
},
{
"classification": "hive-site",
"properties": {
"hive.metastore.client.factory.class": "com.amazonaws.glue.catalog.metastore.AWSGlueDataCatalogHiveClientFactory"
},
"configurations": []
}
]
电子病历版本:
5.16.0
Presto版本:
0.203
