Hive：执行错误选择并同时删除分区配置单元查询

Question

我在同时运行两个查询时遇到错误。

这是场景。

我正在使用AWS EMR，下面是我的hive表架构。

CREATE TABLE India (OFFICE_NAME STRING,
OFFICE_STATUS     STRING,
PINCODE           INT,
TELEPHONE   BIGINT,
TALUK       STRING,
DISTRICT    STRING,
POSTAL_DIVISION   STRING,
POSTAL_REGION     STRING,
POSTAL_CIRCLE     STRING
)
PARTITIONED BY (STATE   STRING)
ROW FORMAT SERDE       'org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe' 
STORED AS INPUTFORMAT  'org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat' 
OUTPUTFORMAT   'org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat'
LOCATION  's3a://mybucket/'
TBLPROPERTIES (  'parquet.compression'='SNAPPY',   'transient_lastDdlTime'='1537781726');

首先运行查询，

SELECT count( distinct STATE ) FROM India;

在查询运行时，运行第二个查询

ALTER TABLE India DROP PARTITION (STATE='Delhi');

并在第一次查询中得到此错误

谷歌搜索后我找到了这个链接

https://docs.aws.amazon.com/emr/latest/ManagementGuide/emrfs-files-tracked.html

因此，无论如何在运行时或第二个查询中的元数据都不会执行，直到第一个状态完成。

请帮我解决这个问题或任何建议，设置任何可以解决问题的参数。
