------------------------------------
Labels: newbie ramp-up (was: )
> impala-profile-tool should support parsing thrift profiles downloaded from
> WebUI
> --------------------------------------------------------------------------------
>
> Key: IMPALA-13033
> URL: https://issues.apache.org/jira/browse/IMPALA-13033
> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Reporter: Quanlong Huang
> Priority: Major
> Labels: newbie, ramp-up
>
> In the coordinator WebUI, users can download query profiles in
> text/json/thrift formats. The thrift profile is the same as one line in the
> profile log without the timestamp and query id at the beginning.
> impala-profile-tool fails to parse such a file. It should retry parsing the
> whole line as the encoded profile. Current code snipper:
> {code:cpp}
> // Parse out fields from the line.
> istringstream liness(line);
> int64_t timestamp;
> string query_id, encoded_profile;
> liness >> timestamp >> query_id >> encoded_profile;
> if (liness.fail()) {
> cerr << "Error parsing line " << lineno << ": '" << line << "'\n";
> ++errors;
> continue;
> }{code}
