Huaisi Xu created AVRO-1797:
-------------------------------
Summary: Schema parser should not expect ctrl-char (ASCII: 0-31)
to be escaped in default value for bytes
Key: AVRO-1797
URL: https://issues.apache.org/jira/browse/AVRO-1797
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.7.4
Environment: Hive, Impala
Reporter: Huaisi Xu
Priority: Critical
In https://avro.apache.org/docs/1.7.7/spec.html#schema_complex, "Default values
for bytes and fixed fields are JSON strings, where Unicode code points 0-255
are mapped to unsigned 8-bit byte values 0-255.". The example provided is:
bytes || string || "\u00FF".
However, if I try to create a table schema with default bytes value for a
decimal field to be i.e. "\u0031", I will have "Illegal unquoted character
((CTRL-CHAR, code 31)): has to be escaped using backslash to be included in
string value.". Anything less than 32 fails.
