--------------------------------------
Summary: The random data generator used for tests repeats the same
value over and over again
Key: PARQUET-1353
URL: https://issues.apache.org/jira/browse/PARQUET-1353
Project: Parquet
Issue Type: Bug
Reporter: Zoltan Ivanfi
The RandomValues class returns references to its internal buffer as random
values. This buffer gets a random value every time a new random value is
requested, but since earlier values reference the same internal buffer, they
get changed to the same value as well. So even if successive calls return
different values each time, the actual list of these values will always consist
of a single value repeated multiple times. For example:
||n-th call||returned value||accumulated list expected||accumulated list
actual||
|1|6C|6C|6C|
|2|8F|6C 8F|8F 8F|
|3|52|6C 8F 52|52 52 52|
|4|B8|6C 8F 52 B8|B8 B8 B8 B8|
