BlazingSQL报错java.lang.IllegalStateException: Unable to instantiate java compiler

在使用BlazingSQL的时候，遇到了下面的错误：

Exception:
java.lang.IllegalStateException: Unable to instantiate java compiler
at org.apache.calcite.rel.metadata.JaninoRelMetadataProvider.compile(JaninoRelMetadataProvider.java:433)
at org.apache.calcite.rel.metadata.JaninoRelMetadataProvider.load3(JaninoRelMetadataProvider.java:374)

File "/root/bsqlserver/gce_app/libs/bsql_util.py", line 22, in jsonstr_bsql_exec
gdf = bc.sql(sql)
File "/usr/local/envs/bsql/lib/python3.7/site-packages/pyblazing/apiv2/context.py", line 2880, in sql
except cio.RunQueryError as e:
AttributeError: module 'cio' has no attribute 'RunQueryError'

可能的原因：在多个地方导入了blazingsql模块
保留一个 from blazingsql import BlazingContext 即可恢复正常
