Hi I forget add this (https://issues.apache.org/jira/browse/PARQUET-1172)
Add this on lira Thank you and regards, Abel ke Abel Ke (RD-TW) <[email protected]<mailto:[email protected]>> 於 2018年1月3日 下午4:48 寫道： Hi I have two parquet files they are made by different way, 1st Use pig load protobuf file then store by parquet pig storer(parquet-pig-bundle 1.9.0) 2nd Use protobuf to parquet and add this patch(https://github.com/apache/parquet-mr/pull/411) or store by spark But when I use parquet pig loader to read 2nd example and describe schema, it show different schema with I use same loader to read 1st case(read example and describe). And when read 2nd example then access tuple I can't use "." to point out tuple content like normal pig script, error message is "Cannot find field name in element:tuple(name:chararray,name2:chararray)”. *read example and describe: 1st case: value:(guid: chararray, blob: (info: {info_tuple: (name: chararray,name2: chararray)}) 2nd case: value:(guid: chararray, blob: (info: {list: (element: (name: chararray,name2: chararray))})) *access tuple: 1st case: B = foreach A generate value.blob.info.name; 2nd case: B = foreach A generate value.blob.info.name; //error message: Cannot find field name in element:tuple(name:chararray,name2:chararray) And I ask Julien, when use 2nd case I can add “.element.” like “ B = foreach A generate value.blob.info.element.name;” to get tuple value, but element is a virtual level, like “ info_tuple”, maybe need add some solution to avoid virtual level Thank you and regards, Abel ke <table class="TM_EMAIL_NOTICE"><tr><td><pre> TREND MICRO EMAIL NOTICE The information contained in this email and any attachments is confidential and may be subject to copyright or other intellectual property protection.
