Hi all,
I´m having some trouble in a production environment with PutParquet processor.
When my flow file has only header + 1-3 records, the PutParquet succeeds, the
file is written in HDFS, but it is invalid. But when the flow file has a lot of
records, the PutParquet processor also succeeds and it is possible to read the
generated files.
I tried to open the invalid parquet files using parquet-tools, hive and
pyspark, and all of them fails with the same error: "Can not read value at 0 in
block -1 in file".
Hive also shows me this error in the log file: Caused by:
parquet.io.ParquetDecodingException: Encoding DELTA_BINARY_PACKED is only
supported for type INT32.
To reproduce the problem, i used a GetFile processor + PutParquet writing in
HDFS, NIFI version 1.11.4
Here is an example of the content of a file that is created, but invalid (i
changed some chars):
timestamp,ggsn,apn,msisdn,statustype,ip,sessionid,duration
1589236199000,186.4.75.1,webapn.company.com,44895956521,Start,177945774,979cdf6b021ed038,-1,
And an example of a success case:
timestamp,ggsn,apn,msisdn,statustype,ip,sessionid,duration

My PutParquet is configured to write files UNCOMPRESSED, version PARQUET_2_0,
and TRUE for avro configs. He is also using a CSVReader as record reader, with
this schema:
{
"namespace": "nifi",
"name": "logs_radius",
"type": "record",
"fields": [
{ "name": "timestamp", "type": "long" },
{ "name": "ggsn", "type": "string" },
{ "name": "apn", "type": "string" },
{ "name": "msisdn", "type": "string" },
{ "name": "statustype", "type": "string" },
{ "name": "ip", "type": "int" },
{ "name": "sessionid", "type": "string" },
{ "name": "duration", "type": "long" }
]
}
And my Hadoop cluster is a standard CDH 5.16.1 installation, hive
1.1.0-cdh5.16.1.
Please, where is my mistake? Or should i open a Jira?
Thank you for your time.
