Project: Avro
Issue Type: Sub-task
Components: java
Affects Versions: 1.7.7
Reporter: vincent ye
Priority: Critical
org.apache.avro.LogicalTypes#fromSchemaIgnoreInvalid lookups and update CACHE.
CACHE is backed by hashmap without synchronization. In a multithreaded
environment, it causes a infinite loop in hashmap lookup. The race condition
problem is described in the following blog

I experience this infinite loop in Spark jobs with high concurrency.
