Antoine Pitrou created PARQUET-2222:
---------------------------------------
Summary: [Format] RLE encoding spec incorrect for v2 data pages
Key: PARQUET-2222
URL: https://issues.apache.org/jira/browse/PARQUET-2222
Project: Parquet
Issue Type: Bug
Components: parquet-format
Reporter: Antoine Pitrou
Fix For: format-2.10.0
The spec
(https://github.com/apache/parquet-format/blob/master/Encodings.md#run-length-encoding--bit-packing-hybrid-rle--3)
has this:
{code}
rle-bit-packed-hybrid: <length> <encoded-data>
length := length of the <encoded-data> in bytes stored as 4 bytes little endian
(unsigned int32)
{code}
But the length is actually prepended only in v1 data pages, not in v2 data
pages.
