Tim Armstrong updated IMPALA-8236: ---------------------------------- Labels: observability (was: ) > Adding new TUnit values to runtime profile is broken > ---------------------------------------------------- > > Key: IMPALA-8236 > URL: https://issues.apache.org/jira/browse/IMPALA-8236 > Project: IMPALA > Issue Type: Bug > Components: Backend > Reporter: Tim Armstrong > Priority: Major > Labels: observability > > See IMPALA-8235 for context. > The problem this tracks is that there's no way to add a new value to the > TUnit enum, which is required in TCounter, without breaking existing readers > (at least Java readers), which will fail to decode TCounter values with an > enum value they don't recognise. > The workaround is to only use the following units in anything that is > serialised into a TCounter: > {noformat} > UNIT, > UNIT_PER_SECOND, > CPU_TICKS, > BYTES > BYTES_PER_SECOND, > TIME_NS, > DOUBLE_VALUE > {noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
