Jon Haddad commented on CASSANDRA-13010:
----------------------------------------
I don't believe this line does what it's supposed to:
{code}
ci.setTargetDirectory(cfs.getDirectories().getDirectoryForNewSSTables().getPath());
{code}
First off, getDirectoryForNewSSTables returns *any* directory that's available
to be written to. The call {{getDirectoryForNewSSTables}} has this comment:
{code}
/**
* Basically the same as calling {@link #getWriteableLocationAsFile(long)}
with an unknown size ({@code -1L}),
* which may return any non-blacklisted directory - even a data directory
that has no usable space.
* Do not use this method in production code.
*
* @throws FSWriteError if all directories are blacklisted.
*/
public File getDirectoryForNewSSTables()
{
return getWriteableLocationAsFile(-1L);
}
{code}
I believe a better way to approach this would be to use
{{SSTableWriter.descriptor}} to pull out the target directory.
