> From Michael Bieniosek:
> {code}I'm trying to do an update row, so I write code like:
> long lockid = table.startUpdate(new Text(article.getName())); try {
> for (File articleInfo: article.listFiles(new NonDirectories())) {
> articleTable.put(lockid, columnName(articleInfo.getName()),
> readFile(articleInfo)); }
> table.commit(lockid);
> } finally {
> table.abort(lockid);
> }
> This doesn't work, because in the normal case it calls abort after commit.
> But I'm not sure what the code should be, eg.:
> long lockid = table.startUpdate(new Text(article.getName())); try {
> for (File articleInfo: article.listFiles(new NonDirectories())) {
> articleTable.put(lockid, columnName(articleInfo.getName()),
> readFile(articleInfo)); }
> table.commit(lockid);
> } catch (IOException e) {
> table.abort(lockid);
> throw e;
> } catch (RuntimeException e) {
> table.abort(lockid);
> throw e;
> }
> This gets unwieldy very quickly. Could you maybe change abort() to
> finalize() which either aborts or does nothing if a commit was successful?
> {code}
