JeongMin Ju commented on PHOENIX-4366:
--------------------------------------
I have experienced similar errors.
I have an error when copying data using the Upsert ... Select statement to a
table with the same schema.
The cause of the error was the encodingScheme variable in the
BaseScannerRegionObserver class.
This variable is [initialized in the preScannerOpen of the
BaseScannerRegionObserver|https://github.com/apache/phoenix/blob/v4.10.0-HBase-1.2/phoenix-core/src/main/java/org/apache/phoenix/coprocessor/BaseScannerRegionObserver.java#L207-L208]
and it is [used in the postScannerOpen method of the
UngroupedAggregateRegionObserver|https://github.com/apache/phoenix/blob/v4.10.0-HBase-1.2/phoenix-core/src/main/java/org/apache/phoenix/coprocessor/UngroupedAggregateRegionObserver.java#L493]
class. In this process, when another query comes in, the value can be changed.
[The encodingScheme and useNewValueColumnQualifier variables in the
BaseScannerRegionObserver
class|https://github.com/apache/phoenix/blob/v4.10.0-HBase-1.2/phoenix-core/src/main/java/org/apache/phoenix/coprocessor/BaseScannerRegionObserver.java#L133-L134]
should not be created as instance variables, but should be used to get the
values at the point of need.
I used version 4.11 but it seems to be in error after 4.10.
The following is an error in version 4.11.
