Hi Nuria,

thanks for the reply. Am I correct in assuming you mean the channel irc://irc.freenode.net/wikidata, or is there a specific analytics channel?

Greetings,

Adrian

Probably irc is better suited for this 

type of question, you have an issue with conversion of types:

" Caused by: java.lang.RuntimeException: Hive internal error: conversion
of string to array<string>not supported yet."

Selecting any of the hours that do not work brings out the same error, you can inspect the table data by looking at files in:  /wmf/data/wmf/wdqs_extract/year=2017/month=8/day=23/hour=9/ 

and try to find the records that have faulty data see if you can exclude them from your query.

You can get data with: hdfs dfs -cat /wmf/data/wmf/wdqs_extract/year=2017/month=8/day=23/hour=8/ and look at it with the parquet-tools command line. As I mentioned earlier probably pinging us on irc would be best.

Hello everyone,

I'm having trouble with the entries in wmf.wdqs_extract on 23.08.2017,
specifically the hours 9-17. The call

hive -e "insert overwrite local directory 'temp' row format delimited
fields terminated by '\t' select uri_query, uri_path, user_agent, ts,
agent_type, hour, http_status from wmf.wdqs_extract where
uri_query<>\"\" and year='2017' and month='8' and day='23' and hour='8'"

works fine, as do all hours in 0-8 and 18-23, but if I change hour to
anything between 9 and 17 it fails with the following message:
