When using UDL, sometimes I meet "JVM while holding global locks". Why this happend?
Here is the SQL used:
create flex external table aim_track_20190210() as copy with source OssSource(path='oss://xxxxxxx20190210*') parser fjsonparser(flatten_maps=false, record_terminator=E'\n');
create table aim_track_test4 as select m1 from aim_track_20190210 limit 2000;
+2Which CREATE TABLE statement generates the error? If it's the second, can you run the SELECT part okay?
select m1 from aim_track_20190210 limit 2000;
+1Could you please share us with UDL OSSSOURCE JAVA code and share us more information on the issue. Is the CREATE flex external table query erroring out?
+1Chen, you meant you ran below statement?
create table aim_track_test4 as select m1 from aim_track_20190210 limit 2000;
was your plan to create external flex table?
