Expected behavior 期望表现

返回正常

Actual behavior 实际表现

{"exception":"class java.io.UncheckedIOException","message":"java.io.IOException: Failed to get result within timeout, timeout=60000ms","cause":"java.io.IOException: Failed to get result within timeout, timeout=60000ms"}
这里的timeout=60000ms 是在哪里设置的,能否调大,出现这个的原因是什么
有时候就重新查询可能出席那下面两个返回
{"exception":"class java.io.UncheckedIOException","message":"org.apache.hadoop.hbase.DoNotRetryIOException: java.lang.NoClassDefFoundError: Could not initialize class org.apache.hadoop.hbase.protobuf.ProtobufUtil","cause":"org.apache.hadoop.hbase.DoNotRetryIOException: java.lang.NoClassDefFoundError: Could not initialize class org.apache.hadoop.hbase.protobuf.ProtobufUtil"},
{"exception":"class java.lang.RuntimeException","message":"java.lang.OutOfMemoryError: GC overhead limit exceeded","cause":"java.lang.OutOfMemoryError: GC overhead limit exceeded"}
能否解释一下这几个是因为什么,
