Chia-Ping Tsai updated HBASE-20119:
-----------------------------------
Description:
The way to add cp to TableDescriptorBuilder is shown below.
{code:java}
public TableDescriptorBuilder addCoprocessor(String className) throws
IOException {
return addCoprocessor(className, null, Coprocessor.PRIORITY_USER, null);
}
public TableDescriptorBuilder addCoprocessor(String className, Path jarFilePath,
int priority, final Map<String, String> kvs) throws IOException {
desc.addCoprocessor(className, jarFilePath, priority, kvs);
return this;
}
public TableDescriptorBuilder addCoprocessorWithSpec(final String specStr)
throws IOException {
desc.addCoprocessorWithSpec(specStr);
return this;
}{code}
When loading our config to create table with multiple cps, we have to write the
ugly for-loop.
{code:java}
val builder = TableDescriptorBuilder.newBuilde(tableName)
.setAAA()
.setBBB()
cps.map(toHBaseCp).foreach(builder.addCoprocessor)
cfs.map(toHBaseCf).foreach(builder.addColumnFamily)
admin.createTable(builder.build())
{code}
If we introduce a pojo to carry the cp data and add the method accepting
multiple cps and cfs, it is easier to exercise the fluent interface of
TableDescriptorBuilder.
{code:java}
admin.createTable(TableDescriptorBuilder.newBuilde(tableName)
.addCoprocessor(cps.map(toHBaseCp).asJavaCollection)
.addColumnFamily(cf.map(toHBaseCf).asJavaCollection)
.setAAA()
.setBBB()
.build){code}
