Generally looks good, but I am confused about the configuration code.
flume-ng-channels/flume-file-channel/src/main/java/org/apache/flume/channel/file/FileChannel.java
<https://reviews.apache.org/r/8379/#comment30405>

    Why do this when you are taking the max of this value and FileChannelConfiguration.FLOOR_MINIMUM_REQUIRED_SPACE later? Did you want to do a Math.max here?

flume-ng-channels/flume-file-channel/src/main/java/org/apache/flume/channel/file/Log.java
<https://reviews.apache.org/r/8379/#comment30404>

    Looks like you are checking for min of the configured value and FileChannelConfiguration.FLOOR_MINIMUM_REQUIRED_SPACE in FileChannel.java and you are checking the max of that value and FileChannelConfiguration.FLOOR_MINIMUM_REQUIRED_SPACE. Doing both these together means that minimumRequiredSpace is always equal to FileChannelConfiguration.FLOOR_MINIMUM_REQUIRED_SPACE. Am I missing something here?

Good catch! We should have been taking the max in FileChannel.

Looks good. I added one really minor comment below. Feel free to ignore. When you are ready, please attach patch to jira.

    Isn't it always guaranteed that minimumRequiredSpace is >= FileChannelConfiguration.FLOOR_MINIMUM_REQUIRED_SPACE since the same comparison was made earlier in FileChannel.java?
