hiveql - Hive index error -


i'm facing issues while building index on multiple columns in hive(0.9.0) table.

describe nas_comps; ok leg_id  int ds_name string dep_date        string crr_code        string flight_no       string orgn    string dstn    string physical_cap    int adjusted_cap    int closed_cap      int comp_code       string

this works :

create index nas_comps_legid on table nas_comps (leg_id) 'org.apache.hadoop.hive.ql.index.compact.compactindexhandler' deferred rebuild;

but doesn't :

    create index nas_comps_legid_compcode on table nas_comps (leg_id,comp_code) 'org.apache.hadoop.hive.ql.index.compact.compactindexhandler' deferred rebuild;  failed: error in metadata: java.lang.runtimeexception: check index columns, should appear in table being indexed. failed: execution error, return code 1 org.apache.hadoop.hive.ql.exec.ddltask

i guess index somehow able recognize first column because failed :

create index nas_comps_compcode on table nas_comps (comp_code) 'org.apache.hadoop.hive.ql.index.compact.compactindexhandler' deferred rebuild;  failed: error in metadata: java.lang.runtimeexception: check index columns, should appear in table being indexed. failed: execution error, return code 1 org.apache.hadoop.hive.ql.exec.ddltask

i checked this issue don't think cause.

think hive not support indexing on partitioned columns.. please check if comp code partitioned column..

as far indexing on multiple columns, should work..

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
