[Hive Metastore] Lock wait timeout exceeded

[Hive Metastore] Lock wait timeout exceeded

New Contributor

Hi, All

I got a error message of 'Lock wait timeout exceeded' in hive metastore as follows;

what causes this problem?

HDP (2.1.2.1)

Hive(1.2.1.2.3)

MySQL(5.6.27)

after googling, I got the following recommendation;

first, add two values in my.cnf and restart mysqld.

this resolution right?

Is it enough to set ONLY 'innodb_lock_wait_timeout' value?

innodb_lock_wait_timeout                              = 300
transaction-isolation                                 = READ-COMMITTED

Is the reason that cause timeout is deadlock possible?

Is there any configuration of Hive to be changed?

Re: [Hive Metastore] Lock wait timeout exceeded

could you please try query after increasing innodb_lock_wait_timeout to 600, restart of mysql db required in this case.

Current value is default value, innodb_lock_wait_timeout = 50.
