1 year ago 看堆栈，是一直在等待子查询返回，单独查询子查询呢？
SELECT code FROM b_index where someType ='ttt'用/_nlpcn/sql接口查询附带子查询的sql后，后续的部分查询会超时。
es版本：7.13.4 jdk版本：1.8.0_201
sql示例： SELECT count(*) FROM a_index where someCode in (SELECT code FROM b_index where someType ='ttt')
查询sql后，jstack可以看到一个永远等待的查询线程： "elasticsearch[node1][transport_worker][T#13]" #54 daemon prio=5 os_prio=0 cpu=30.68ms elapsed=2456.56s tid=0x00007f9ce8010800 nid=0x785d waiting on condition
