In this case:
1. creating table with regions .
2. zk crashed ( My cluster has 3 zk process , when leader crashed)
3.creating table failed.
I had found the code:
Please confirm whether it need fixed?
for(HRegionInfo newRegion : newRegions) {
// 1. Set table enabling flag up in zk.
try {
assignmentManager.getZKTable().setEnabledTable(tableName);
// This function throw exception.
} catch (KeeperException e) {
throw new IOException("Unable to ensure that the table will be" +
" enabled because of a ZooKeeper issue", e);
}
// 2. Create HRegion
HRegion region = HRegion.createHRegion(newRegion,
fileSystemManager.getRootDir(), conf);
// 3. Insert into META
MetaEditor.addRegionToMeta(catalogTracker, region.getRegionInfo());
// 4. Close the new region to flush to disk. Close log file too.
region.close();
region.getLog().closeAndDelete();
}

What exactly happened here? As much as I enjoy reading logs, I also
enjoy short descriptions of the context of what I'm looking at.
