Question

虽然在cassandra中错误地给两个索引指定了相同的目录路径（ directory_path ），但是在删除索引时可能会产生错误，因此创建新索引。并能够删除指向唯一的不同目录路径的其他索引。请分享您的想法，即如何删除指向现有索引相同目录路径的新索引。

新索引

CREATE CUSTOM INDEX inbound_idx ON inventory.inbound (p_index) USING 'com.stratio.cassandra.lucene.Index' WITH OPTIONS = {'schema': '{
        fields : {
            symbol    : {type : "string",case_sensitive: false},
            destination  : {type : "string",case_sensitive: false},
            ticket_id  : {type : "string",case_sensitive: false}

        }
    }', 'refresh_seconds': '1', 'directory_path': '/c05/stratio_index/inventory/inbound'};
CREATE CUSTOM INDEX inbound_idx_new ON inventory.inbound (p_index_new) USING 'com.stratio.cassandra.lucene.Index' WITH OPTIONS = {'schema': '{
        fields : {
            symbol    : {type : "string",case_sensitive: false},
            destination  : {type : "string",case_sensitive: false},
            ticket_id  : {type : "string",case_sensitive: false}                       
        }
    }', 'refresh_seconds': '1', 'directory_path': '/c05/stratio_index/inventory/inbound'};

错误：

inventory_admin@cqlsh:inventory> drop index inbound_idx_new;
ServerError: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.NullPointerException
inventory_admin@cqlsh:inventory> drop INDEX inbound_idx;
ServerError: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.AssertionError: attempted to delete non-existing file inbound
inventory_admin@cqlsh:inventory> drop index inbound_idx1;
inventory_admin@cqlsh:inventory>
