During the daily operation we have a large number of WriteTimeoutException and ReadTimeoutException errors. In the logs of Cassandra we can see that the read and write timeout errors are also recorded with the error: _Java.lang.RuntimeException: java.lang.RuntimeException: org.apache.cassandra.exceptions.ReadTimeoutException: Operation timed out - received only 1 responses._ *+Log Detail, Application Level:+* _22:54:22,945 [ERROR] AbstractEntityManager - Insert object 'Event{...}' error com.datastax.driver.core.exceptions.WriteTimeoutException: Cassandra timeout during write query at consistency LOCAL_QUORUM (2 replica were required but only 1 acknowledged the write)_ *+Log Detail, Cassandra Level:+* _EBUG [SharedPool-Worker-6] 2017-08-24 08:36:40,114 StorageProxy.java:1893 - Range slice failure; received 0 of 1 responses for range 1 of 1 java.lang.RuntimeException: java.lang.RuntimeException: org.apache.cassandra.exceptions.ReadTimeoutException: Operation timed out - received only 1 responses._ The timeout error occurs 2 seconds later because of the configuration in the yaml:+underlined text+ _# How long the coordinator should wait for writes to complete write_request_timeout_in_ms: 2000_ -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
