Zoltan Ivanfi created PARQUET-1191: -------------------------------------- Summary: Type.hashCode() takes originalType into account but Type.equals() does not Key: PARQUET-1191 URL: https://issues.apache.org/jira/browse/PARQUET-1191 Project: Parquet Issue Type: Bug Reporter: Zoltan Ivanfi
If two Type instances are equal according to equals() but have different logical types, then both of the following cases are possible: * The two instances may accidentally have the same hash, which is consistent with the equals() method but is pure coincidence and has a very low probablility. * The two instances may have different hashes and end up in different buckets of a hash map, leading to a situation where we can't find a value in the hash map despite that it's equals() would return true. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
