How to add split point to table with valid key.
Hi,
I need to get the table split points and get the AccumuloRowId from that
key.
Does anyone know how to do that?
i already tried the
TableOperations.addSplits(String tableName,
SortedSet<org.apache.hadoop.io.Text> partitionKeys)
method. But it seems added splitpoint key are not valid.
Thanks and regards.

Ah. This is a geowave specific class. Hopefully someone in the geowave
community will see your message. If geowave has their own mailing list, you
may want to ask again there.

hi thapliyal,
here the code sample,
try {
Collection<Text> list = op.listSplits("accumulo.metadata");
System.out.println(list.size());
ArrayList<Text> ll = new ArrayList<Text>(list);
System.out.println(ll.get(0));
AccumuloRowId id = new AccumuloRowId(new Key(ll.get(0)));
} catch (TableNotFoundException | AccumuloSecurityException |
AccumuloException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
And output,
1

Can you clarify what you mean when you say you "try to create
AccumuloRowId object". Can you share that part of your code, and the
error message you received?

hi thapliyal,
yes. listspilts give me the list of split point keys. But when i try to
create AccumuloRowId object it give me an error saying invalid key.,
any solutions?
Thanks and regards.
