Hi All,

we have a cluster system which consists of 3 nodes with 2 data nodes and 1 management node. SQL nodes are running on data nodes also.

when we try to update tables we get these errors :

java.sql.SQLException: Deadlock found when trying to get lock; Try restarting transaction message from server: "Lock wait timeout exceeded; try restarting transaction"
