Daniel Kulp resolved AVRO-2179.
-------------------------------
Resolution: Fixed
Assignee: Daniel Kulp
Fix Version/s: 1.9.0
For 1.9.0, I've added a system property of
"org.apache.avro.limits.string.maxLength" that can be used to set a maximum
string length to read for Utf8 strings.
> Malformed data, the BinaryDecoder allocates large arrays

> Recentlly I use avro find it has this problem:The memory suddenly explode and
> trigger the fullgc, So I dump the memory file. And then I use jvisualvm tool
> to analysis I found a org.apache.avro.util.Utf8 object and the bytes array
> length was over 1610470037.
> The method of readInt() shouldn't over limit, So I think it should be
> restricted.
