I'm new to Phoenix and encountered a problem. Firstly, I created a table with 30000000 records by java on Phoenix. Then, I want to create a phoenix global secondIndex to the table. But, when the program runed for 10 minutes, the java client throws SQLTimeoutException. I don't know why, Please help me.
java.sql.SQLTimeoutException: Operation timed out.
