> Project: Accumulo
> Issue Type: Bug
> Components: start

> Priority: Trivial
> Labels: newbie
> Fix For: 1.6.2, 1.7.0

>
> We handle initializing a new instance by calling a utility method on each of
> the metadata and root tables. That utility method ignores the passed table id
> and instead sets the initial table configs for each of the metadata and root
> tables.
> That means we end up setting them twice. I believe the action is idempotent
> (since we're using the same values each time), so no failure should result.
> {code}
> public static void initMetadataConfig(String tableId) throws IOException {
> try {
> Configuration conf = CachedConfiguration.getInstance();
> int max = conf.getInt("dfs.replication.max", 512);
> // Hadoop 0.23 switched the min value configuration name
> int min = Math.max(conf.getInt("dfs.replication.min", 1),
> conf.getInt("dfs.namenode.replication.min", 1));
> if (max < 5)
> setMetadataReplication(max, "max");
> if (min > 5)
> setMetadataReplication(min, "min");
> for (Entry<String,String> entry : initialMetadataConf.entrySet()) {
> /* XXX There should only be one of these, and the table id should
> be the one passed in.
> */
> if (!TablePropUtil.setTableProperty(RootTable.ID, entry.getKey(),
> entry.getValue()))
> throw new IOException("Cannot create per-table property " +
> entry.getKey());
> if (!TablePropUtil.setTableProperty(MetadataTable.ID, entry.getKey(),
