Error while processing statement: FAILED: Error in acquiring locks: Locks on the underlying objects

[#1]

Hello guys, thanks for reading this and hope you can help me with this issue.

I am new at Cloudera, and i am following a little tutorial trying to create a external table from a log file in Hadoop.

I executed this statement in Hive:

CREATE EXTERNAL TABLE intermediate_access_logs (
    ip STRING,
    date STRING,
    method STRING,
    url STRING,
    http_version STRING,
    code1 STRING,
    code2 STRING,
    dash STRING,
    user_agent STRING)
ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe'
WITH SERDEPROPERTIES (
    'input.regex' = '([^ ]*) - - \\[([^\\]]*)\\] "([^\ ]*) ([^\ ]*) ([^\ ]*)" (\\d*) (\\d*) "([^"]*)" "([^"]*)"',
    'output.format.string' = '%1$$s %2$$s %3$$s %4$$s %5$$s %6$$s %7$$s %8$$s %9$$s')
LOCATION '/user/hive/warehouse/original_access_logs';

I was waiting too much time for the statement's result but finally i had this error message:

Error while processing statement: FAILED: Error in acquiring locks: Locks on the underlying objects cannot be acquired. retry after some time

I do not know what means 😞

Hope you understand.

Execute the below commands , to have a better insight. 

SHOW LOCKS <TABLE_NAME>;
SHOW LOCKS <TABLE_NAME> EXTENDED;
SHOW LOCKS <TABLE_NAME> PARTITION (<PARTITION_DESC>);
SHOW LOCKS <TABLE_NAME> PARTITION (<PARTITION_DESC>) EXTENDED;
 

Does you hive supports concurrency ? 

hive.support.concurrency = default (false)

Are you using HiveServer2 ?
