tinkerrrr opened a new issue #7344: URL: https://github.com/apache/incubator-doris/issues/7344
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Version 0.14.0 and 0.15.0 ### What's Wrong? I was going to upgrade Doris from 0.14.0 to 0.15.0, it performs well during the upgrade process. But a complete upgrade plan of production environment should contain degradation plan. When degrade from 0.15 to 0.14, FE crash with excetion: ``` java.io.EOFException at java.io.DataInputStream.readFully(DataInputStream.java:197) at org.apache.doris.common.io.Text.readString(Text.java:415) at org.apache.doris.catalog.Catalog.loadMasterInfo(Catalog.java:1580) at org.apache.doris.catalog.Catalog.loadImage(Catalog.java:1479) at org.apache.doris.catalog.Catalog.initialize(Catalog.java:760) at org.apache.doris.PaloFe.start(PaloFe.java:108) at org.apache.doris.PaloFe.main(PaloFe.java:60) ``` This could reduce the confidence of upgrading ### What You Expected? Guarantee compatibility between FE 0.14 and FE 0.15 ### How to Reproduce? upgrade from 0.14 to 0.15 and then degrade from 0.15 to 0.14 ### Anything Else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
