does it also ban transitive dependencies on log4j and slf4j-log4j12?

Yes, if you do not want to ban transitive dependency, just add |

The latest reload4j version is 1.2.18.3 with a few additional vulnerabilities fixed. |

I'm not sure about this part, but the rest LGTM

Basically in addition to replacing reload4j, the PR also simplifies dependency management. |

can you also verify the test failure is unrelated? |

I am testing my Hadoop reload4j patch, and then realized there are a lot of gotchas when building downstream applications. |

For HBase we have tried out best to not introduce log4j dependencies to our downstream users, they will only pull in slf4j, so I do not think it will break our users too much. But it is true that hadoop and zookeeper will introduce log4j and slf4j-log4j12 dependencies to downstreamer users, I suggest we do a round of cleanup, to avoid introducing these dependencies. Thanks. |

Oh, I see, some extra refactoring?

I don't have a strong opinion about this so will approve the PR but it would be better to stick with just the changes that are implied by the description [HBASE-26691 Replacing log4j with reload4j for branch-2.x]

So do we plan to use reload4j for 2.x, or we plan to directly upgrade to log4j2? |

how about we get this in place for branches-2 now, so that we can stop shipping hbase 2 releases with an EOL log4j 1, but we plan for the log4j 2 changes to be the preferred path for whatever the next minor 2.x release is after the backport lands. (presuming the testing goes well.) |

Merged. Agreed, we can do this now and I will pick it all the way back to branch-2.4, and anytime we can commit log4j2 work when ready to branch-2.5 and branch-2. |

I also committed an addendum that ups the reload4j version to the latest release at this time, 1.2.19, and fixes a couple of misses in shading and assembly configuration. |

The child POM does not inherit the exclusion of the dependency introduced by the parent POM. Is the reconstruction safe? What are the considerations for deleting the exclusions?
